Sort of! I get this weird sensation when I lay my head all the way back and close my eyes. After a couple of minutes, I get this forceful sensation in the center of my head that feels like a quick spinny/vibrational type feeling and it always makes me open my eyes. A couple times, it's so intense that I jolt up a little and I feel my heart racing afterwards and a little warm. It's not apnea or that dream-feeling where you fall and suddenly wake up. I started experienicng this the night of my injury. Doctors seem clueless.
