I mean yeah, it's entirely possible that every time we fall into REM sleep our conciousness is replaced. Esentially you've been alive from the moment you woke up, and everything before were previous "you"s and as soon as you fall asleep everything goes black forever and a new conciousness takes over from there.

It may seem like this is not the case just because today was "your turn."

We don't have a way of telling if we genuinely experience passage of time at all. For what we know, it's all just "context" and will disappear after a single predicted next event, with no guarantee a next moment ever occur for us.

(Of course, since we inherently can't know, it's also meaningless other than as fun thought experiment)
