This is what happens when people still have a desire to believe in a metaphysical reality, but want to reconcile that with their understanding of physical reality. It's assumed that ghosts are real actual disembodied spirits of the dead because belief in them serves a cultural need, but in a modern society not entirely governed by magical thinking, such beliefs don't seem practical enough to be comforting. The attempt to move past "superstition" and ground the supernatural in science was the driving impetus behind the spiritualism movement (that and grift.)

You see the same incentives in the modern day with Biblical literalism and flat earth, and UFO folklore where "ultraterrestrial" and "interdimensional" theory shows up. It seems like science if everything you know about science comes from Reddit and TikTok but it's really just three space goblins stacked in a lab coat. Three because, of course, three is a sacred number.

There's no explanation for why ghosts wear clothes that isn't less ridiculous than the obvious, that it's because we imagine people wearing clothes, and ghosts are imaginary people.
