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

Question

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.

Anesthesia means you’re asleep. Analgesia means without pain.

Both of these are done so You don’t remember the surgery, nor feel it.
