paranoia in my closet

When I was 11 i moved into a house across town, upgrading from the trailer we were in. It was amazing, until I woke up sweating one morning, eyes trained on my closet door, unable to understand why I was so scared, but knowing it was because I felt someone staring at me through my closet door. I didnt find out until 9 years later that after I had ran out of the room my little brother woke up to our closet door being open.
