I'm curious if anyone experienced something similar. Recollection of this experience is coming back to me from time to time. Time to share it somewhere public.

An infinite speed on a geometric loop nightmare.

I would ride a simplifed car, on a string loop, suspended on 4 points in air. Forming a sagging square in a void. I would slowly accelerate, going up & down on the parabolas.

The acceleration would be accompanied by ever growing sense of dread, until I would be flying around the loopz making a lap more than once a second. It would physically hurt, with my body tense, I would wake up screaming.
