That's so insane! I didn't know it had a name... but I did that once when I was alot younger.
In my dream I remember thinking things were so real... yet something was very very wrong... I can't remember how I figured it out, but I realized I was dreaming... therefore invincible... I jumped off buildings and did all these crazy things because I wasn't afraid of anything.

If I could just do that again... hmmmmm
