Also, I don't understand how stupid people in horror movies are.
1) Fight back. Find I weapon or something and actually fight back. More than 1/2 the time the killer is some loser that if somebody stood up to them they could totally take them.
2) If you don't want to fight back. Actually find an intelligent place to hide, its your house, you know every place to hide and should be able to do so...or run and seek assistance from a neighbor or friend or anyone.
