Ok so heres what happens. Occasioanlly i will wake up in the middle of the night and i will shut my eyes to go back to sleep. After about a minute or 2, i will feel like everything is spinning and i never knew what it was so i would just open my eyes and it would seem to stop. Then i would try to go back to sleep and sometimes it would happen again and sometimes it wouldnt. I was just wondering if this had anything to do with dreaming or if it was just a head rush or something.
