That’s a very interesting turn of phrase that “the world is starting to seem strange”... Would love to see an essay on that!
You’ve never experienced it? Best description I can offer is, it’s sort of like deja vu, familiar but somehow warped. You know it’s just “off” somehow, at times obvious and at other times not so obvious. Remember those old time travel movies, where they unintentionally caused some change and returned to their time to find it different, in sometimes surprising and unpleasant ways? Like that. I guess once you reach a certain age, you actually are a time traveler of a sort. I’m not all that detached, I’m very computer literate, I have and use a smartphone, I like all sorts of music new and old. But, I’ve found myself increasingly ill at ease with what I see in the world at large. Hope that makes some sort of sense, lol.
