I've Started To Sense Spirits

I'm 13 years old; (soon to be 14) and these strange occurrences have been happening since my 13 birthday. Basically I've started to sense thing no one in my family can; spirits. I see black shadows from the corner of my eyes, here breathing, been feeling cold spots on my body (arm, forehead); gotten held down in bed by someone while another spirit was starring me down at the head of my bed. Sometimes I even hear my name being whispered or other things I can't make out.

I've also been seeing glances of the past. For example; I was in my bathroom when all of a sudden I saw a huge house and maids walking down one of the porches. I've never seen this house before but as I looked around it seemed to be the area where a historical building is in my town. After that I looked up my town's history and bingo! There's the house, but before it was rebuilt.

I've also looked at a picture of a old canoeing race that happened almost one hundred years ago; and I started to see it, as if I was one of the girls on the side lines cheering the guys on. I even had on the types of dresses they wore. After about 10 seconds it went away.

I also sometimes (every couple of weeks) see what's going to happen. When I'm lying in bed in the morning have a wake I sometimes see the entire day; basically every single thing that going to happen, and then it does. Though it doesn't happen that often; though I tend to have deja vu a couple of times a week.

And for the first time (for both)

1) When I meditated for the first time I saw my great-grand-mother.

2) Today I kept thinking about my grand mother and her going to Scotland and how I which I didn't say no to go with her; when I got back home from school, my mom was talking to her, about it.

If anybody knows what's going on with me; I would love the help, it's kind of getting scary. Thanks!
