So I Was Reading A Fic (as One Does), Specifically One About Time Travel, And It Made Me Realize How

So I was reading a fic (as one does), specifically one about time travel, and it made me realize how weird that would be if it happened. Like, just imagining a future version of myself suddenly appearing in the middle of my living room while I'm reading a book or smth that would freak me out I would actually have no idea what to do-

And in fics where there aren't any superpowers in that universe, it's probably so weird for the characters bc it would be similar to our real life. I've just been thinking about that lol
