Going Crazy Or Psychic?

Ever since I can remember I have been able to see white glows around every body and everything. The first layer around the person is translucent and outlines everything, including fingers, nose, teeth etc. The rest of the layers are just a bright white glow getting more and more faded as it expands. A bit like an aura but with no colours. Sometimes I see a glow just on it's own and if I stare at it long enough a face comes out. Whenever I look at them I get this really unusual, sad feeling inside my stomach.

The scariest thing that has ever happened to me was when I was in the bathroom brushing my hair when a glow appeared behind me. The second it appeared this same name would repeat in my head over and over again. I recognized the last name because it was my friend's last name and the next day at school I asked that friend whether she had a dead relative or something by that name. When she said she did and that it was her great grandmother's name I felt scared. I also get Déjà vu more than three times a week. When it happens I feel as if I've seen what is happening before in a dream or something but aren't quite sure. I'm even able to sometimes guess what people are about to say.

When I look around let's say a room and concentrate I see white and translucent grainy lines and stuff everywhere. It's easily ignorable but when ever I focus on it I tend to zone out and hear a humming noise. I also hear the humming noise whenever I read a book and it's frustrating.

I want to know what is wrong with me. I don't drink alcohol or take drugs so it's not because of that.
