Sounds med related to me. Agree with moose - enjoy the experience. You had a creative burst whatever the reason, and that's your interesting memory to keep. I know psychosis can turn ugly but that one sounds very cool!

One of my most intense hallucinations was when I tried lexapro. Swirling rainbows - but I was in an int'l airport having flight anxiety so it turned bad. Looking back, too bad I wasn't just somewhere else and enjoy it. I like rainbows lol.
