Neurological or not, hearing random voices just wants me out of that state asap.

I have regular sleeping hours due to work.

Haha yeah, it's something pretty scary.
Just focus on the fact that it's just your body fucking up when it happens.

If you've had it only once, it's probably not serious. If you keep having it a lot, you should get it checked out. More people than you think have encountered it, it's just not well researched.
