I know this is going to sound strange, but I'm almost positive I was actually visited by Tommie's ghost last night.
Seriously... I was lying in bed asleep, and I could hear like my mom's voice in the back of my mind say, "Tommie?" Next thing I know, I actually feel something furry fly past my face, and then, I feel this big fur ball right next to my head, yet I also experience that same "zap" you experience whenever there's a spirit present and feeds off your energy level. When I finally woke up and opened my eyes, of course, everything was normal.
I actually wonder though, why exactly do spirits feed off of your energy? I remember back in the summer of 2008 when I kept having nightly encounters with a spirit, I wanted to actually communicate with it, but I, of course, couldn't because I couldn't move or anything, as I was just zapped.
