Sounds like a fractal shape or kaleidoscope shape (which are kind of fractal? not sure).

I was remembering that when I had really good sleep, both on waking up and falling asleep, though not always, I'd see kaleidoscopic patterns all across my field of view while my eyes were closed. It was interesting but they moved around too much to be able to memorise them exactly. Sometimes I could still see them when I opened my eyes but only very briefly.
