I experience these kinds of “hallucinations” all the time by practicing mantra meditation (similar to Transcendental Meditation). I see those jellyfish swirls and Winamp visualization type effects within minutes of beginning to chant the mantra. I have no particular knowledge of the effects of these visuals but I find that they make meditation more enjoyable. It gives me something engaging to hold on to while sitting in silence.
