Last Night

Last night, I was sitting in my bed reading for school. I had the bedroom door wide open and was home with just Orion (who was sleeping in his crib) and Lexie (who was downstairs watching TV). As I was sitting there reading, the door suddenly creaked as if it had moved. There was no draft. Just a moment later, I heard the floorboards at the foot of my bed creak. I continued reading with my head down and saw white appear in the bedroom doorway as if someone was walking into the room. I immediately looked up and no one was there.
