alt Hacker NewsI'm wondering if "geometric nightmares" is a reoccurring dream I've had since I was a kid too, basically two cog-wheels linked with each other, but one is extremely huge and the other unbelievable tiny. I'd never describe this as a "geometric nightmares" though, but it does kind of sound similar.
Maybe there is something about "contrasts" as they all seem to be vaguely related to "big difference" basically.
I've heard these fever dreams referred to as big-small as well. I believe it's the same phenomenon. For me it was pillars from high up above, where they're all the same width, but one is also much bigger at the same time. Hard to explain... Just an odd feeling.
And, anecdotally, I have gotten a similar feeling reaching deep enough meditation.
