The same things has happened to me!
One time, I was dozing off to sleep with the lights off in my room, and I felt someone get in my bed, but when I looked around, no one was there. I went back to sleep, but then I felt someone slowly get in my bed, trying not to wake me up, and then I started hearing clicking and typing. When I woke up the next day, my friends all started calling me and asked wtf kind of messages I was sending them, but I was sleep though, so he was using my computer, and probably looking at posts on MJeol!:lol
The next time, I was home alone with my dog, and then he started barking, then the entire house shook, and I heard faint screeching, then my dog started yelping! I remember MJ saying he's afraid of tiny dogs, so he probably ran from him. :lol
I would also hear whispers everywhere, and I'd ask who's there, and the whispers would get louder, but I don't understand them.
And one time, I was scanning through the forums on my mom's laptop, but it went into hibernation, but when I went to turn it back on, I saw MJ's face, instead of my reflection, looking back at me through the shiny screen! I screamed and closed it, but when I opened it back up, my reflection was there. Scared the crap outta me!
And when I go to sleep, I'd see him sitting over my bed, watching tv, occasionally with a bag of popcorn, sitting on a nonexistant chair that covers my entire body. He would occasionally glance at me, but remained so focused on the news. When I move, he holds onto my wall, fearing he would fall on me. And right before I wake up, he'd look at his watch, get up, removing the chair, and would disappear.
These moments have been very frightening for me, but I really like having his presence around me. I don't want him to leave yet.
Yeah, I'm being selfish. :lol
