This may just be my imagination, and I have a very active imagination, so there is no definite stuff, but, a couple nights back I was laying in bed staring at the wall, trying to get to sleep. I didn't get to sleep that day, but that is beside the point. It was midnight or around midnight, and I felt like somone took ahold of my shirt and pulled, not that hard, but pulled, three times. Other times I think my Mom is behind me trying to get my attention, because I feel a slight sensation, like somone running their finger on your arm, and then I know my sleeve moves. If it isn't my imagination it must be my best friend who recently passed away joking with me, because, she and I would always joke "When I die, I'm going to haunt you"
