One night I just got done reading some really scary stories and what made it worse is that my door opened seemingly on its own not long after!
Hahahaha, it's really scary to read scary stories at night.. I had that experience 
Everyone must have at least once in their life. I checked to see what opened the door and it was just my cat pushing it open haha.
Hahaha, you thought it was a ghost right?? 
Oh absolutely!
