Maybe five weeks after finishing #Undertale, late one night when I was talking via telegram to my late lamented 2nd partner K., I had a...well, a _vision_ is the only way I can put it. I hesitate to call it a "hallucination", partly because it was largely a tactile experience, and it was something I could dip into and pull out of, not like anything else I had experienced at the time (although I've had a few similar experiences since). It was a complicated, multi-part experience, and it _felt_ very powerfully "spiritual" in that indefinable way. (http://monophylos.livejournal.com/3405.html talks about it a bit.)
