Search for "cosmic despair" as one of four types of states (along with "cosmic unity", "cosmic struggle" and "rebirth"). "Cosmic despair" captures states that go under various names, including "the dark night of the soul", visions of hell related to absolute desolation (rather than lava and stuff), existential dread, and quite a few other names and concepts in religion, spirituality, and philosophy. And describes a very specific type of bad trips. The concept comes from "Realms of the Human Unconscious: Observations from LSD Research" by Stanisval Grof, the grandfather of the research on psychedelics in therapy. He relates these states to four stages of birth, which he takes literally. My preference is to take it metaphorically, though.
