When I was a kid, I did a break and enter, and had these coins. A grown man took the coins saying he'd get the money for me. Later we were in a bar, and I said where's the dough? He pulled out a 20 dollar bill, and tore it in half.
The thing is how do you know things like "Russell Brand was stalking me" are true when you acknowledge that you've had instances where you were out of your mind?
I had some experiences on drugs where I was sure I was right and then figured out later that I wasn't. I think it's the same thing. A chemical thing.
