Can You Tell Me If I'm Psychic?

First I took a few test's on how psychic I am, and it usually came up with high. So I did some research and finding out, and it turns out, that I am telepathic and a clairvoyance. So I asked my friend over MSN to think of a object, and revolve it in her head. I said what I thought it was and I got it! Then, I got these numbers, turns out, they were hers, her brothers and sisters birthday date! I also got the name of a different friends grand dad. Earlier, I got a vision that I will bump into my friend looking for me when I walk out the door. I did! And a vision that the bell will go before I finish the last question and it happened. I have also had paranormal experiences, which I can't explain. Like plates crashing together, but no one down there. And this 'shhhh' noise in my ear when I wake up in the night for no reason, and the feeling of being watched. My friend was amazed with what I could do, and so was I! I was so amazed when I finally did it, and I am happy with my blessing. But I don't know why I have it, and I would love to know why, is it because of my fox like nature? Or the fact that I like Nature? It's hard to explain, but when my friend asked, I just said, 'well, it's just natural really, a talent but rarer than others. It is just their you know? Just comes into mind and then, pop, it happens. Mind power I guess.' We talked about it for a while and she is always wanting to know how and why it was me, and to know more and what I can do. I do think that I am Psychic, and usually see the future around 20 seconds before they happen. So what do you think? Am I psychic? Or just crazy? Any I have some tips?
