You wake up completly covered/soaked in blood and no memory of how that happened. What would be the FIRST thought to go through your head?
Fear that I am seriously injured
Fear that I murdered someone
Fear that this is going to lead to HIV infection
Pure mindless disgust
Amusement - this must be some kind of prank!
Apathy - back to sleep you go
Paranoia that someone is about to frame me for a crime
Fear that I am going insane and hallucinating
Fear that I have pissed of the mob and this is a threat
