I can't bring myself to believing things like that. I mean, yeah I do, but then no I don't. It's just an on and off kind of thing. My cat doesn't really do that kind of stuff and I don't really see things. I used to get real paraniod when I was a little kid, but now I kinda grew out of it. When I'm home alone, I start getting all crazy. My cat is outside, and I'm the only one in the house. I'll run down the hall to the kitchen to go fetch myself a glass of water, and out of the corner of my eye, I'll see something on the couch. I turn my head to look at the couch, and there's nothing there. So I'm think "Ok, calm down. It's just your imagination, there's nothing there." I'll do something to entertain myself like go on the computer when I'm home alone, just to distract me when from getting crazy again.

Once, I ran down the hall to the kitchen again, and I past the laundry room. The doors pushed opened at me, and I just stood there, looking at the door, freaking out! I told my parents and they're like: "HAHA, Kid, you're crazy!! It's just all in your head, chill out." So ya know, I chill... and chill... and chill... Sometimes I'm supposed to be sleeping but I play around with my electronics and my eyes are focusing on my eletronics, I see something buzz by my bedroom door. There's no noise, the figure is a human figure and everyone else is asleep (or awake). I got pretty freaked out once, and texted my friend. And he's all like: "Boo!! There's a creepy dude in your house!!"
Nothing major really happens around my house, just some minor things, then I tell myself it's not real. I get over it pretty easily. Whenever I watch a scary movie, I freak out for a couple of days and I kinda get paranoid and think that the Grudge is gonna come out and kill me. When I really get scared is around 12:27... when the wife & husband find discover the grudge when they accidentally ran our a black cat (Grudge 2). It's been a year since I've seen it, but sometimes when I think about it, it bugs the heck out of me when I'm trying to fall asleep.
But I can tell you one story: My sister's friend's dog is a little "not normal" sometimes. My sister's friend would be home alone, and the dog would just be there, laying on the floor. Then he'll look at something... and then raise his head to look at the ceiling as if he was starring at something.
People tell me stories, I get a little paranoid if it's like, SUPER SCARY. But I can't bring myself to believing it's actually real.
