I would consider this to be two separate, semi-related concepts asserted together, one that consciousness is an illusion, and one that you are a different person each day.
The first point draws many questions; consciousness is an illusion of what? What mechanism causes the illusion? How does it cause it? Why does the illusion exist? And you may note that you could replace illusion in those questions with consciousness and be left in a similar (though still distinct) place. So simply calling consciousness an illusion seems to me to kick the can down the road without actually addressing the problem.
As for being a different person after a lapse in awareness, I’d like to take it a step further and say that you could be considered a new person with every change in moment. It’s easy enough to look back 10 years and say “yeah, that’s a younger me, but they’re not the same as me I can just see the path that led to where I am now.” Getting closer, you may feel different today compared to yesterday depending on various factors (sleep, diet, events), but are you a different person because you slept and had a lapse of awareness, or because the state of your mind and thoughts have shifted? When your internal monologue (or equivalent thought) asks “what is this guy talking about?” Is it not thinking “what” in a brand new context given the words it is responding to, forming a new beginning to a thought that puts the mind in a unique state primed to then enter a new state of “is?” And if the mind is in a unique state of novelty, could the person attached to the mind be considered distinct from the person that existed before?
There is a reason the word revelation exists, it indicates when a person has a novel thought that changes their perspective or way of thinking, altering who they are. Would they not be a new person despite being aware of the process of their change? Due to the above points I don’t think new personhood only occurs at sleep, but constantly. The rate of change may quicken or slow, but the change is always there.
