...'me', in the sense of the breathing person sitting here...

I am not just playing with semantics when I say that the belief we have of a continuous 'me' is illusory. We really have no one 'me'. At any particular time we have the accumulated memories of our past, to give us the impression of a single me. That 'single' person changes constantly, morphing and breaking throughout life.

The person who wakes up from sleep is no more and no less you than the person who wakes up in a virtual world. The thread of consciousness was broken by sleep. Two new yous begin, as you have begun anew each day.

Perhaps my next post explains it better.
