Won't happen in total darkness. Also, it's happened in full daylight. Like all the sudden someones head just looks absolutely massive, like I've lost the ability to perceive size. I find the effect pleasurable so I kinda zone out and let it happen. Otherwise I can snap myself out of it pretty quickly.
