According to a quiz, if I was a ghost, I would be...
a Poltergeist! :)
Always the prankster, poltergeists are known for their loud and aggressive behavior. If you're anything like this mischievous spirit, something tells us you don't mind being the class clown.
While you might not be able to levitate objects off the ground (a common characteristic of poltergeist behavior), things may take flight when you're around--snowballs, spitballs and maybe even food? Your friends probably appreciate your wacky sense of humor and spend a lot of time reveling over your latest hi-jinks.
Just make sure you know when to cool it; a poltergeist's behavior can get annoying after a while. There is a reason silence is considered golden...well, sometimes.
