Ancestory History Or Just Me

Ever since I was born I was able to see more than what an average person could. I didn't know the word "Psychic" Till I was 7-8, I was very much interested into spirit things, and saw my first Spirit when I was 5. It looked like my dad, But it wasn't, Especially when I could run right through it, Well Now I am 12. And I feel angry sometimes or sad, or hyper outta nowhere, and nothing would cause me to feel that way, I can see future events and past events That I never was there for. I get almost like Daydreams of things I never seen before, like 3 times I got a price right, down to the cent, I can guess an age of a thing, And I had a daydream of a mining tunnel or something like that exploding from methane gas about 1-2 months ago, and I saw it happened when I watched the news one day. My dreams make everything seem realistic, Like I am in a tragedy of something. My most recent one was a truck driving (The truck was from Georgia) with these almost like wire things that looked like they were 60-70 feet tall hanging off the bottom of the truck to. And I was driving a car talking on a cellphone I never seen before, And the almost like wire things went right through the windshield and killed me. I know the feeling of death, I sometimes will be just be laying in my bed and feel like I can breathe very little, like my chest locks up or something... I can sense a spirit's presence, and sometimes see them, but they mostly look shadowy. I wonder to myself how I got this gift if nobody else in my family did... I barely know ANYTHING about my ancestor's, My gift expands more everyday, And I feel like I can't tell anybody in my family, or they'll look at me like I went completely cracker's, My mom seems like she is but I am not quite sure, My sister isn't psychic, my grandmother isn't, nobody I know is! And I do not know who my Ancestor's are either. Is there anybody out there, that can tell me if I do or not? Because I have no clue how I am a Psychic first off, And how I am more than just one kind of psychic.
