I don't think it's medical. What I saw was something like this videoVoxel Octree Raytracer - CUDA editbut everything was made of gold, silver and crystal and the shapes were more complex and less repetitive. I only see such things briefly and with both eyes closed. You know those light patterns you see when you close you eyes? It's as if they were getting brighter, crisper and going 3D. They are acquiring structure, form, pattern.Very trippy stuff.
Very trippy stuff.
Maybe it's just a side effect of ammonia vapors rising from the litterbox
