> Are we unconscious when we sleep I don't think that is the right question to ask. Sleeping person is unconscious almost by definition. They don't respond to stimuli and they don't do much of anything besides breathing and just laying there. > do we merely lose the capacity to remember? That is a better question.

(For example it happened multiple times to me that noises happening around me where incorporated into my dreams in various forms.) So if sleeping were just amnesia then these dream memories would need to be explained somehow.
