He, i have the same 'problem'. In daily life i'm pretty peacefull but in my dreams i havce slit peoples throat, drugged them ( when they tried to
drug me), fought like some deranged cagefighter, flown, used telekinesis, been a wizard of some kind and whatnot.
But in my case, i devoured comics in my youth, love series like heroes and other ones like it and read fantasy/sci-fi literature on a regular basis so
i know where it could come from with me. So your not the only one in this and it still are just dreams, like the movies only more interactive
