> My mind also drifts to very strange things, like wondering how I would know if my consciousness is not annihilated every night, and all of my memories are not simply deposited into a new brain in a new simulation (but not "me") in the morning.

It's gotten a bit better as I've grown older, but I used to get pretty severe insomnia from the fear that my "self" would be destroyed when I lost consciousness and the "self" that awoke would simply be a perfect duplicate.
