Basically, I'm writing a story that involves beings of 5 spatial dimensions visiting Earth. And when I say "writing" I mean "putting thoughts down on paper as they come to me" or almost that, i.e. not much thought has gone into world-building. Mostly 5-dimensionality manifests in crazy transformations of architecture and vehicles, and psychodelic walking into completely different places while apparently staying still. Also, as a map gets infinite increase in stuff when it's tranformed into a globe, the 5d Earth has much more geography than our 3d Earth, but for some reason most of the extra geography is barren, except for, lately, some lichen and giant fungi (a half-formed reason for that might be that only those fungi have a mutation allowing them to travel in additional directions). Additionally, the story is inspired by Doctor Who, so the 5d beings look completely like humans (except maybe for wings that are maybe the part of them that extends into the other dimensions, or there is more to them than is seen) And finally, 5 dimensions could be an overkill, but 4 seemed to be too pedestrian at the start, plus if I did 4 it would be too easy to assume that I mean space and time, but they make plotting a mess, because as I understand it, at any moment my characters can end up anywhere in space (if not in time, but I didn't want to copy Doctor Who completely). It all seems to me to be almost incoherent, but I wonder, if via a few generous cuts and edits, the world could make a bit more sense*, and if anyone here would have any suggestions as to how that might be accomplished. *That is, put more "science" into "science fiction".
