Oh, I understand, heart.

In trying to understand what these small explosions with sounds inside my brain were, I would try to imagine what it could be.

Also, you do it then start awake and realize all is OK...drift back off to just do it again! When I do it, I do it 5-10 times before I eventually go to sleep.

I read one explanation (neurology) that the brain is still firing and trying to shut down for sleep and our body gets ahead of it so we feel this firing still going on and that anxiety makes it worse. That makes sense to me.

It was so confounding to me because I'd never heard of another soul doing this. Of course, I'd seen others do the sensitory sleep starts...body jerking...as if falling and knew that was common. I didn't know these were along the same lines and it helped me to know.

I can only explain it as small explosions with sound, a sizzle like sound, similar to the sound you hear when you're close to professional fireworks being set and they fizzle out in the sky? That type of sound. It's so bright inside my brain, but in just a small area if that makes sense. It jerks me immediately awake. I used to scare me to death. Now it's just a jerk as I associate knowledge immediately as to what's going on and remind myself that I'll do it a few more times...lol.
