I have an example I think, that I've been curious about!

Every few years I experience a recurring nightmare, where I am being chased by some kind of giant monster, but I've never gotten a look at what it is and I don't know specifically what it wants but always just assume it wants to do me harm. After a long time running from it and panicking, eventually I realize no matter how hard I try to run, it's futile - the monster will catch me eventually. So I just decide to accept there's no way out and give up. Either I jump off a cliff to go ahead and kill myself (in which case I always wake up before hitting the ground), or I just stop, sit down, and begin to turn around so I can finally get a look at the monster before it catches me (in which case I always wake up before it gets me, AND before I can see it).

I have scary dreams sometimes, but this is the only one I'd classify as a real nightmare. Nevertheless, I find myself waiting for the nightmare to come again, because I really just want to finally get a look at what it is that's chasing me.

Sometimes I wonder if, when I finally get to see it, I'll somehow be changed as a person.
