How Do I Learn To Use It

I am only 13 years old, and I have had so many different things happen to me, I have had dreams that have come true so many times that it can't just be a coincidence sometimes when I don't know a number to something random numbers pop into my head and they are usually right when I am at school I take tests and if I don't know the answer somehow my questions get answered and the answer pops into my head and I automatically know the answer and sometimes I don't know why this happens but when something is going on in my real life not a dream I feel like this thing whatever is happening I feel like I have experienced before the exact same way like people use the same words and use the same actions it all seems so familiar but it seems like it is just out of reach and I don't know why I feel like it has happened before maybe it's because it's happened in my dreams and I don't remember but I don't know why that happens to me and nobody that I know of has ever had any psychic powers the only thing that I can think of is my grandma got a vudu doll once but she got rid of it I don't know if that might be part of the reason why but it could possibly be sometimes when I go to a certain place I feel like I am mentally attached to that place like I've been there before but I ask my parents and they say that I have never been to that place in my life anyway I just want to know if I'm psychic or not and if I am I would like to know how to control all of these different things I don't know if you could suggest somebody to call please help
