Why do we not feel pain under general anesthesia? Is it the same for regular sleep?

I’m curious what mechanism is at work here.

Edit: Thanks for the responses. I get it now. Obviously I am still enjoying the discussion RE: the finer points like memory, etc.

I’ve never had a surgery, and my biggest fear is that if I have one I will feel absolutely everything without being able to move/react. But once you “wake up” from it it’s erased from your memory so you can’t remember the nightmare you just went through.

I’m sure this is not the case, but the thought has crossed my mind more times than I’d like to admit.
