Need Confirmation That I'm Psychic

I am only 13 years old. Sometimes I have feelings when I know something will go wrong or sense that someone is watching me. I don't know what it is but sometimes I think of something and it's like I sent it to the other person because they say my same thought. My mom says none of this is real but I believe different. Sometimes when the phone rings I get this feeling I know who it is and I'm right.

In my dreams it's like deja vu because sometimes the very same thing happens the day after or a week later. It sometimes frightens me because its overwhelming. One I was dreaming and my friend got hurt at a school activity, then on the day of the event she hurt her ankle. Another thing that happened was I dreamt ok I know this is going to sound weird but I dreamed of a girl falling down her stairs and the next day at school the girl I saw in my dreams had a cast on, I walked up to her and asked what happened and she said she fell down the stairs. I was confused the whole day I thought I was going crazy!

Another thing is I walk through the school hallways all the time and when a friend is behind me trying to sneak up on me I address them to the right name and tell them to quit it. Some are really surprised and so am I when I always guess the right person. Once on a school test I wasn't prepared or even ready but a week later I got the quiz back and aced it I was in pure shock I didn't even study!

So what I'm trying to say is, am I psychic? Please someone with any answers please comment me!
