The ‘you’ that wakes up tomorrow is a whole separate entity from you right now, unless you want to concede that identity is a path variable and that whether the exact same physical/mental/emotional entity is you or not depends on how those particles got there.

Just because the brain doesn't form memories while you sleep, doesn't mean you have ceased to exist. You have probably forgot many things that have happened to you today: does that mean you didn't exist in those moments you forgot? Am I misunderstanding your point?

If the universe was created 5 minutes ago, then you didn't exist before that, but it doesn't matter, because past and present don't interact.
