I've had this too, but I think it might actually be a form of deja Vu. I'll get the feeling I've done something before, and then remember I had it in a dream. The thing is, I had never recalled having that dream prior to the feeling of deja vu. So it does feel as if I foresaw the future in a dream, but it's more likely that my memory is being altered somehow. Hate to de-romantacize the experience for you, but I personally don't believe in psychic stuff. ;D
