Well, this isn't going to make me sound like the manliest individual ever, but I think I need to tell it to someone. A few weeks ago, I was driving home from work. It was late. i was tired. So I wasn't my usual self. I was singing along to some song when all of a sudden I glanced up and saw two eyes looking back at me, and at the time I didn't know whos eyes they were so I was scared to death. I slammed on my breaks, in the middle of the road, jumped out, and was ready to run... I mean fight whoever was in my back seat. Long story short, I saw my own reflection in the mirror. 
It seems to happen to me at least once a week. If I watch a scary movie or show then it happens at least every other day until I forget about it, lol
I have gotten better. I don't have to sleep in my parents bed anymore. Granted, I am 32 now, lol
