Very rough treatment for a hypothetical Poltergeist house, I scribbled this down while watching it:
Façade
The Freeling House, with the tree and storm, Star Spangled Banner playing
Scene 1—They’re Here
The Freeling bedroom, mannequin Carol Anne in front of TV, strobes from static, light shining from top of TV into the wall above the bed (which shakes—re-used effect from Exorcist)
Scene 2—Tree attack
Tree branches inside room grabbing Robbie, can go back and forth (controlled by scareactor)
Scene 3—Dragged in
Carol Anne mannequin attached to bed post screaming, air blowing into closet, potential strobes
Scene 4—Skin peel vision bathroom
Marty lunges at you with most of his face peeled off (vision)
Scene 5—The light
Massive skull puppet out of doorway
Scene 6—Clown doll
Maybe a room full of clown doll statues?
Scene 7—The monster
Ghost monster outside the bedroom
Scene 8—The pool
Rain effects seen in Ghost Town 2, skeletons surround you
Scene 9—Portal
Carol Ann and Robbie’s bedroom again, portal opens up with tentacles coming out, bed shaking
Scene 10—The dead rise
Yard, coffins protrude from the ground and the dead reach out at you from all sides
