Missing Scene??? It's Driving Me Crazy

I don't think you are remembering it correctly at all. The only WTF face she gives is when she is dropped off and sees the cut phone wire across the gate. She sees it and then gives the WTF face, looks to see if her friend who dropped her off is down the road, opens the gate, walks past the switch with blood, doesn't see that, and then the next scene is her running out of the house screaming "MURDER! MURDER!". No version I have ever seen shows her in the house. There would be no reason for her to flip the lights up and down because the power was never cut in the house. Not in the book and not in the movie. In the book it describes her going straight to the kitchen after unlocking the door and trying the phone, then after it being dead she walks to the living room and saw the steamer trunks with blood on them. she saw blood everywhere, but she didn't see the entire living room. She didn't see past the couch, obviously didn't see Sharon or Jay. She looks at the door which is open a bit and sees more blood. She then sees a body on the lawn. She then turns and runs back the way she came and then past Steven Parent. I believe she only saw two bodies.
