Our consciousness-selves with our current memories will be gone since our consciousness-selves are created by brain processes. Our brains disappear when we die.
But we will return to the exact same state after we die that we were in before we were born, so our chances of experiencing the same conscious-self again is exactly the same it was before we were born into our current bodies.
If someone thinks it is impossible to experience the same conscious-self again, then they think that nature somehow magically keeps track of which conscious-self has already existed to prevent a return. How would that work?
If the multiverse is infinite in time or size, our conscious-selves are guaranteed to return.
