I NEED HELP ON SOMETHING THAT HAPPENS WHEN I FALL ASLEEP?

Yep that has happened to me and it's scary. It's aggravated by panic. Try to go with it, almost detach yourself from it, as if you are watching yourself. Relax into it. Know that you are not dying, going into a coma, or any of the other thoughts that go through your mind. Trust your body to take care of itself. It will pass much more quickly that way. Hope that helps.
