I think i'm physic but i'm not completely sure.?

i'm only 13 years old. now when i was 8 i watched a man overdose from heroin. then on the same day that mans best friend died from and over dose of heroin but in a different house, he died in my house. the one i witnessed died was in a motel. anyways ever since that night i have realized that i can see parts of the future in my dreams. some examples are:i had a dream that there was going to be a new kids at school. i already knew him. i tries to talk to him but my friends wouldn't let me. now the next week or so a kid that cam from earlier in the year came back and every time i tried to say hi my friends would interrupt me and i never go the chance to. i had a dream that there was this building. it was made of bricks in the back and a new kind of material in the front. i had a sense that it was a school. kids were working out in the front. then i was driving home from my track meet and saw the same building. now let me explain. i saw the same building in my dreams coming home from a track meet. the track team was for my school. now in my dreams the building was a school. people were working out. we just got done running a track meet. now i had that dream way before track start so i guess it meant that i was going to do some sort of sport from my school. now there is about 8 or 9 dreams i have had like that. then sometimes i have feelings. as in like some body is going to die or something really bad is going to happen. example: it was my moms patients birthday party and i had a feeling someone was going to die ( the same feeling i had when the two people overdosed). i though my moms patient was going to die but it turns out my boyfriends uncle died that same night. many other things have happen like that. people i need help. if i explain to you. you may not understand but after i think about my dreams something VERY similar happens. i tried to talk to my very close friend but i know she doesn't believe my. now i don't have anybody to talk to about it. there is so much more behind all thins that is to personal to put online. i can even believe in putting this, i'm in d esprit need of help. Please explain to me what is going on.
