I was telling my uncle about this thread and he told me about an experience he had a couple of years ago. He took his wife and two boys to his boss's beach house in Florida for a weekend trip. My cousins were 7 and 5 at the time and the younger one was notorious for waking my uncle up for a drink of water in the middle of the night. That night my uncle woke up to, what he thought was my cousin, tugging on the covers down near his feet. When he sat up in bed, there was no one there. My uncle went to the other bedroom and found both boys passed out in bed. He went to back to bed assuming my cousin had given up on the water. The next night, around 2:00 am, my uncle once again woke up to someone tugging on the covers at his feet. He turned on the bedside lamp and, other than he and my aunt, there was no one else in the room. He checked on my cousins and they were both sound asleep. At this point, he is a little freaked out and wakes the boys up asking them if they were in his room. They both said no and went back to sleep. He checked all of the doors and windows and the house was definitely locked up for the night. When he got back to the office on Monday morning, he hesitantly told his boss about the tugging of the covers. His boss had a huge look of relief on his face and he proceeded to admit to my uncle that it happens to him every time he's stayed in that room but he wasn't sure if his mind was playing tricks on him. Apparently about 10 years ago, before my uncle's boss bought the place, a little boy died in that room from a ridiculously high fever. Now every time a family stays in that room, the little boy tugs on the covers and wakes up the dad.
