Power Stealer?

So here goes. I think that I steal people's psychic powers. It's a very confusing subject but I think I really do. When I was about 8 or 9, my adoptive brother Sam told me that he had received a message in his sleep stating that the two of us had just gotten psychic powers. Ours though are based more off of an "elemental" sense. I can mainly control the wind, and he can control the water.

Once, when I was twelve, the two of us were practicing our powers together on the beach and his suddenly stopped working. Then mine changed. Instead of wind, I was using water. It startled me a lot. So I tried to give them back but I simply couldn't. Eventually though, they left me, and returned to him, safe and sound. I've always had wind as a power but I constantly get new powers in addition to wind that I've never had before come to me, stay for about a year, then leave forever.

Last year I could kind of predict the future with feelings. Once I got one so strong that just from the feeling, I could pretty much tell exactly what was going to happen. See, my friend Andrew and I were about to sit down to lunch. We sat with a group of friends who played the game Spray at lunch, where you fill your mouth full of Powerade and people tell jokes until you just can't stand it anymore and laugh, spraying everyone with Powerade. Well, we were about to sit down to lunch and I saw where Andrew was going to sit and I got a very strong feeling that he shouldn't sit there. Then, a bunch of random things popped into my head about what might happen, I said them outloud, and a few minutes later they all came true. James sat directly across from where Andrew and I were going to sit and sprayed ALL OVER. Which would have drenched us in spit and Powerade.

Back to being a power stealer. That power of being able to tell the future through feelings, came out of no where, and left me when I over used it, and so have many others. Does anyone have any ideas as to what I am? There's probably an actual label for it besides what I call it.
