I've been getting dizzy lately before I go to bed, like very dizzy. You know how when you're drunk and you have the spins? It's like that. Well last night as I was trying to get to sleep I keep going into these "modes" as I'll call them where I can't move even though my brain is trying to. It's like my brain and body aren't attached to each other. I try to call for help but I can't. Then I will get out of this "mode" somehow with much struggle and then it will happen again and again as I try to sleep. It's a very scary situation, what might this be?
