user12385: 
Last year I experienced samadhi, full state of awareness. Mind's
  thoughts stopped for days and I can't describe with feelings and words
  the complete experience.

It was like the wheels of my mind stopped. I was living the present moment very loud. It was like I was standing on top of my head and my conscioussness was dramatically expanding. 
I wasn't practicing anything and I had no idea what it was until someone who was in the same state since his birth explained to me.

Before come to this, a few days ago I had some scary lucid dreams
  with dream paralisis.
Then 11:11 synchronicities on my clock

I've seen light in the dark. And it was not coming through my eyes.
The experience of samadhi lasted a few days and it had a curve and a peak. I felt like the third eye was openned. And I still can't believe that I'm talking about all these things.

In it's peak I felt like I was living in the moment for first time in
  my life.

There was no past or future, it was just now. 
And everything was so calmful and alive... and there was nothing to worry about. 
And I knew that I could be whoever I wanted to be no matter what. Like I was in deep sleep since I was a kid and I finally woke up.
I knew that I could change and improve and manipulate my body and my mind like a toy.
No skills, no title, nothing was impossible, it was just a matter of choice.
I felt like everything including me were connected. 
It is difficult to describe exactly how I felt... but  It was like i could feel the vibrations of everything around me from a distance. I could hear high frequencies when someone was focusing in me. I could see green auras orbiting in the air.
I was looking the world outside and everybody was like zombies of their own minds. And I realized that I used to be like them too. 
Everything was so clear and easy to understand without thinking at all, like in Limitless movie.
It was like I was sleeping in my entire life and I finally woke up in the real world. 
Everything was so real... I had no good or bad feelings, no thoughts, just consciousness in an epic level I didn't know that ever existed.
I was looking the trees, the birds and the fountain like I had never seen anything like this before. And they were stunning.
No word was coming in my mind, no thought, nothing. But I could easily participate in a high quality conversation without using my mind at all. But I didn't want to talk, I just wanted to listen. For first time in my life I wanted to listen... ONLY!
But I had my senses increased at 100000% and I felt my body and my mind like a cheap version of my real self. I felt my body like a human avatar for my soul. I was not sure about god etc... till then. I realized that everything is much more than we understand. 
My body and my mind was like a toy. On top of my head with a distance of the physical body was my new self that could easily manipulate my physical mind and body just by desire.

So... what was it, where it came from and why?   and last but not
  least... what's next?


user12386: Eckart Tolle describes what I understand as a spontaneous awakening in his book “The Power of Now.’ His experience was not within the context of Buddhist meditation practice, and for me it misses the connection and explanations of an individual ‘experience’ to Buddhist teachings. Though American Zen Buddhist often adopt the ‘no scriptures’ rebellion of monks forced to endlessly recite and memorize scriptures, I believe study of Buddhist scriptures is beneficial to American Buddhists in order to build framework of reference for walking the Buddhist path. In short, it might be good to look to Buddhist teachings to put your experience in that framework. Then again, you could work with your experience within any frame of reference, or none or none.

user7090: Show compassion for others. If you really have achievement you can benefit others very easily.

user9861: Beyond any doubt you have had an extraordinary experience that has the marks of Enlightenment as defined by Theravadin Buddhism. However, I doubt your experience was that of samadhi (which sometimes follows Enlightenment), because you clearly had some insights, such as “Like I was in deep sleep since I was a kid and I finally woke up,” “I felt like everything including me were connected,” “I was looking the world outside and everybody was like zombies of their own minds. And I realized that I used to be like them too,” “It was like I was sleeping in my entire life and I finally woke up in the real world,” “I was looking the trees, the birds and the fountain like I had never seen anything like this before,” and “I realized that everything is much more than we understand.” Where does it come from? From a traditional point of view, it had to come from having had similar experiences over many lifetimes. Why? Your core intelligence (Bodhicitta) has the function of bringing you up to speed asap. Very few confused or maladaptive sankhara stood in your way, allowing your core intelligence to cause you to experience key insights that were already present in your core intelligence, which is ordinarily unconscious. What is next? The traditional Theravadin answer is you study the Abhidharma. For more information about that path, you can read by book, The Path of Love.

user11518: While I have never had such an experience that lasted for days, I have had some rather zen moments upon reaching epiphanies during contemplative thought. I think the longest was about 15 minutes long and happened when I realized the true nature of the universe. 
Again, not during meditation but during a period of "focused unfocusing". I would simply relax, get rid of all external stimuli, and play a ringing bell tone. Once there I'd follow any thought down its' rabbit hole and see where it leads me.
No single procedure regarding resting and focusing the mind covers all the ways it may occur. You may have your own self-learned method or stimuli that brings you to a similar or (obviously) greater point. Consider me suitably impressed, but not surprised. We all have our particular strengths - maybe this one is yours? 
I'd certainly explore it further. No matter what your faith or beliefs being able to focus your mind in such a manner will have a myriad of benefits. 
Learning things about your mind is a significant step forward in humanity. Congratulations!! Enjoy the ride.

So... what was it, where it came from and why?

What you have described sounds very much like the experience of Udayabbaya ñana or the knowledge of Arising and Passing Away. You can search for these terms and figure out more about this. You can also refer to this description of this stage by Daniel Ingram.
As to where it came from, only you can answer that question. Something you undertook, like self-enquiry might have resulted in this. Generally these things are unclear at that time but with sufficient understanding of oneself and the world, it can become more clear.
Why did it happen? Because it is natural, it might present itself to any one who looks inside. For some it may not happen with years of practice, but for some others it can happen by just looking at things with mere curiosity. There could be various reasons for this, ranging from past karma to genetic differences, but its not worth pondering too much on these as these are outside one's control anyways.

what's next?

Spectacular as it may be, it is not the final stage or end result of one's insight practice. In fact, some texts like Visuddhimagga refer to it as the beginning of actual insight practice. The long term goal is to use this to reach stream entry, or the first stage of awakening. To get there you might need regular practice and most probably also guidance from an experienced teacher.
In the short term, it is better not to hold on to these experiences, as it is transient and not repeatable. The clarity might not remain same and identifying with past experiences can cause added suffering. As clarity fades, you might find yourself in difficult territories, so learning and practicing letting go will probably help a lot.

user8157: Buddhist meditation is not clinging to (i.e., not getting infatuated about) experienced phenomena. 

Last year I experienced samadhi, full state of awareness. Mind's
  thoughts stopped for days and I can't describe with feelings and words
  the complete experience.

This is a type of samadhi. Samadhi is the absence of thoughts, just like an orange is orange in colour. Why are you making a bid deal about something that is totally normal? 
Samadhi is the absence of thinking therefore why have you now engaged in a path that is totally the opposite of samadhi, which is thinking about samadhi rather than dwelling in samadhi? 

It was like the wheels of my mind stopped. I was living the present
  moment very loud. It was like I was standing on top of my head and my
  conscioussness was dramatically expanding.

The thinking of the mind stopped. Consciousness expanded. This is normal. But now the wheels of the mind have started up again by asking these questions. 

I wasn't practicing anything and I had no idea what it was until
  someone who was in the same state since his birth explained to me.

I think anyone who believes they have been in samadhi since birth is probably crazy. I would ignore them. 

Before come to this, a few days ago I had some scary lucid dreams
  with dream paralisis.

Dreams are just mental fabrications. In sleep, spiritually, changes of consciousness can occur due to changes in neurology. Whatever happened is just ordinary. Nothing to be infatuated with.

I've seen light in the dark. And it was not coming through my eyes.

This does not matter. What matters is to view all experience with equanimity & non-attachment. 

The experience of samadhi lasted a few days and it had a curve and a
  peak. I felt like the third eye was openned. And I still can't believe
  that I'm talking about all these things.

The impression here is of reading too many books & imagining too many things. If the mind really had samadhi for 3 days, the mind would be calm. 
Did you take drugs? 

In it's peak I felt like I was living in the moment for first time in
  my life.

Again, reading too many book, maybe by Eckhart Tolle. 

There was no past or future, it was just now.

In reality, there is no real past & no real future. Why are you flabbergasted over what is real? 

And everything was so calmful and alive... and there was nothing to
  worry about.

Your mind does not sound calm to me. 

And I knew that I could be whoever I wanted to be no matter what.

Yep... as i suspected, reading too many books or listening to too many gurus. 

Like I was in deep sleep since I was a kid and I finally woke up.

If you woke yup, why are you asking these questions on the internet?

I knew that I could change and improve and manipulate my body and my
  mind like a toy.

If so, what are you not controlling your mind, now? 

No skills, no title, nothing was impossible, it was just a matter of
  choice.

Wow... you sound brainwashed by some new age teachings. Again, if you could do the impossible, why are you here asking these questions? 

I felt like everything including me were connected.

You felt like you were Jesus Christ or Sai Baba, it sounds like.

It is difficult to describe exactly how I felt... but  It was like i
  could feel the vibrations of everything around me from a distance. I
  could hear high frequencies when someone was focusing in me. I could
  see green auras orbiting in the air.

The "I", "I", "I", is getting tedious and unrelated to Buddhism. There is a Hindu forum you can ask your question on, if the mind is unable to give up delusions of "I".

I was looking the world outside and everybody was like zombies of
  their own minds. And I realized that I used to be like them too.

But now you are the next Messiah & World Saviour? Now you will write books, make videos, be a guest on Oprah and have thousands of zombies follow you as your disciples? 

Everything was so clear and easy to understand without thinking at
  all, like in Limitless movie.

If so, why now without understanding? 

It was like I was sleeping in my entire life and I finally woke up in
  the real world.

You sound confused to me & lacking peace. When my mind 1st experienced peace in meditation, it remained peaceful after that. I was amazed peace actually existed because previously I felt there was no such thing as peace. Meditation was about "peace" to me rather than about "awakening". I think you have been reading too many books or listening to too many gurus. When the mind knows peace, it remains dwelling in that peace & that peace is a functional (rather than dysfunctional) state. 

Everything was so real... I had no good or bad feelings, no thoughts,
  just consciousness in an epic level I didn't know that ever existed.

The infatuation currently occurring to your mind shows your mind did have good feelings, otherwise you would currently not be drunk on whatever experience you imagine you had. 

I was looking the trees, the birds and the fountain like I had never
  seen anything like this before. And they were stunning.

If they were stunning, there was good feelings. 

No word was coming in my mind, no thought, nothing. But I could easily
  participate in a high quality conversation without using my mind at
  all. But I didn't want to talk, I just wanted to listen. For first
  time in my life I wanted to listen... ONLY!

So what? 

But I had my senses increased at 100000% and I felt my body and my
  mind like a cheap version of my real self. I felt my body like a human
  avatar for my soul. I was not sure about god etc... till then. I
  realized that everything is much more than we understand.

As I said, reading too many books. Avatar & soul are not related to Buddhism. 

My body and my mind was like a toy. On top of my head with a distance
  of the physical body was my new self that could easily manipulate my
  physical mind and body just by desire.

Mentally, you currently appear unstable; sounding like you believe you are the many manifestations of Krishna or Brahma. 


So... what was it, where it came from and why?   and last but not
  least... what's next?

Why don't you ask your friend who has been in samadhi since birth? Otherwise, if you wish to practise the Buddhist path, simply let it all go; simply stop clinging to whatever experience the mind had; which means giving up all of the "spiritual materialism/egoism" that is currently occurring. Whatever was experienced is the past and the past is now over. Remember, you claimed there was no past. In Buddhism, if a beneficial mental state cannot be maintained then it is worthless.
In summary:

Samadhi (lucid unified consciousness) occurs when the mind stops thinking & lets go, which can occur in  formal meditation, spontaneously or when people take drugs. That is what it is & that is what it came from. 
In Buddhism, what is next is always the Noble Eightfold Path, which is based in abandoning craving, attachment & manufacturing egoism towards every experience without exception. What is next is Nibbana or Peace. 
What is not next is believing: "I am God", "I am World Saviour", "I am Awakened", etc. In Buddhism, what is next is not "I am". "I am" is a belief found in Judaism, Christianity & Hinduism but not Buddhism. Buddhism teaches "anatta", which means "not self". The Buddha taught:


The eye is not yours: let go of it. Your letting go of it will be for
  your long-term happiness & benefit... The ear... The nose... The
  tongue... The body... The mind is not yours: let go of it. Your
  letting go of it will be for your long-term happiness & benefit...
  Whatever arises in dependence on mind-contact, experienced either as
  pleasure, as pain, or as neither-pleasure-nor-pain, that too is not
  yours: let go of it. Your letting go of it will be for your long-term
  happiness & benefit.
Na Tumhaka Sutta: Not Yours

Whatever was experienced is the past and the past is now over. Remember, you claimed there was no past. In Buddhism, if a beneficial mental state cannot be maintained then it is worthless.</p>

<p>In summary:</p>

<ol>
<li><p>Samadhi (lucid unified consciousness) occurs when the mind stops thinking &amp; lets go, which can occur in  formal meditation, spontaneously or when people take drugs. That is what it is &amp; that is what it came from. </p></li>
<li><p>In Buddhism, what is next is always the Noble Eightfold Path, which is based in abandoning craving, attachment &amp; manufacturing egoism towards every experience without exception. What is next is Nibbana or Peace. </p></li>
<li><p>What is <strong>not</strong> next is believing: "<strong>I am</strong> God", "<strong>I am</strong> World Saviour", "<strong>I am</strong> Awakened", etc. In Buddhism, what is next is not "I am". "I am" is a belief found in Judaism, Christianity &amp; Hinduism but not Buddhism. Buddhism teaches "<em>anatta</em>", which means "<em>not self</em>". The Buddha taught:</p></li>

<blockquote>
  <p>The eye is not yours: let go of it. Your letting go of it will be for
  your long-term happiness &amp; benefit... The ear... The nose... The
  tongue... The body... The mind is not yours: let go of it. Your
  letting go of it will be for your long-term happiness &amp; benefit...
  Whatever arises in dependence on mind-contact, experienced either as
  pleasure, as pain, or as neither-pleasure-nor-pain, that too is not
  yours: let go of it. Your letting go of it will be for your long-term
  happiness &amp; benefit.</p>
