Sleep picking?

This may sound a little odd, but I actually wake myself up at night picking. I definitely do it in my sleep, and I wake up at random times with my hand at my head and my scalp bleeding. I do it a lot during the day, and I think that it's such a habit that I now do it in my sleep. It's really affecting the rest that I get. I tried to wear gloves, but they would always come off. I tried the same thing with a hat and that always came off too. One night I used really strong tape and taped gloves to my hands but in the night, the urge was so strong, I woke up and practically tore the gloves off and proceeded to pick for the rest of the night without sleep. Anyone else have this problem??
