Since the start of this year, I have been experiencing headaches and dizziness. This happens when I'm extremely tired. When I wake up in the middle of the night, I cannot open my eyes. Yet, I feel as though the whole room is spinning. Sometimes, i feel myself floating (not literally). I cannot move any of my limbs at all. My whole body is rigid. This usually lasts for 10 - 15 minutes. I'm fourteen. I'm really worried that this might be the start of something serious. I would really appreciate it if anyone could help me figure out this problem. Thanks so much!
