Legitimate Halloween Party Idea's?

hmm, i would say like have a haunted house like leading up to the house where the party is gnna be, like the people have to get through the scary part to go to the part. and then at the party you could get like a few friends to dress up as something scary and like stay in character all night, like not act like themselves at all...that could be freaky....OR...in the middle of the party when everyone's having a good time, turn off all the power in your house and freak everyone out. :)
