Fear of going crazy, and being in a dream like sate!?

I've experienced many of the same things as you. Even now I feel like I'm in a dream sometimes. I used to worry about just completely losing it someday but it hasn't happened yet. After some research I read something that was really comforting. People that really are crazy don't realize they are. Therefore they would never post a question like yours. So I hope that helps you out a bit. Just try to keep your mind off of it and go with the flow. Try not to over analyze every good thing that happens. Life is real. This is real. I am real.
