There is a scene near end where Gage's father awakens, stumbles out of bed, falls and hits his head on the corner of the night stand. Between the nightstand and the bed is a white pillow. They zoom the camera in on him so you can't see the background by the bed and when the camera goes back the pillow lying sideways is GONE! I think it was an error, as he is not seen holding a pillow at all and it disappears momentarily after he has winced in pain from hurting his head.
