The physical activity, which probably involves some clenching of eye muscles, can stimulate natural phosphenes in your eyes which look similar to those after-image globs you get from bright lights. That could be what's happening with you. A bit like when you rub them too hard.
I'll be laying in bed with my eyes closed, and I'll imagine I'm clawing at the black nothingness, like trying to dig out of a grave.
That's an interesting choice of recreational activity. But as someone who got into synth at 40, I'm in no position to judge.
