I thought about this a lot. I tried comparing going to sleep and sleeping to being put under. The only differences I have is that after waking up sometimes I have a recollection of having dreams. But if something happened and I died in my sleep I would not know any better.
Depends on the anesthesia. General anesthesia actually does knock you out for real -- literally shuts down the parts of the brain where we believe consciousness resides.
