Is There a Creature That Fuses With Another Creatures?

I made it as illuminating to think of some case that I can't even fully understand. And from that, I'm learning something about my actual sense of self or sense of identity, continuity. Whereas if you do what Hume does or a lot of Buddhist texts and you just say, well, really interrogate your own experience,. What is that thing that's overt above it? If you can't find anything, well, okay, that's fucks with me, but not because I can't decide whether our Richard prime at time four is the same as Richard Asterix at time eight. All of a sudden, that's not illuminating to me anymore. That's not telling me anything.
