I think the point about unconscious states was not that you "become no one", but rather that it is an interruption to the continuity of consciousness. As a thought experiment, imagine you were magically replicated during sleep such that, at the time of replication, both "you"s were completely physically identical. Both would wake up thinking that they are the same person that went to sleep, but now there are two of them. Are either/both/none of them "you"? My answer would be that they both are, and don't think there's anything special about our physical selves, nor any reason that we're limited to being singletons (to give a code analogy). The combination of our physical self and our cumulative experience and memories are what defines "us". Thinking of identity in possessive terms and the desire to think of ourselves as unique is a quirk of psychology, I think.
