Abstract: This essay presents a systematic catalog of consciousness-related phenomena reported across cultures, historical periods, and social contexts — phenomena that do not fit cleanly within reductive materialist models and that mainstream inquiry has largely excluded from serious consideration. The catalog documents and organizes recurring classes of human experience that have been taken seriously by philosophical, spiritual, medical, and cultural traditions throughout history. By making visible the breadth, structural coherence, and cross-cultural independence of these reports, it establishes that the evidential landscape relevant to consciousness is far larger than dominant frameworks acknowledge. The essay does not argue for any particular metaphysical conclusion. But it does argue that the accumulated pattern of exclusion is epistemically consequential — that what has been systematically ignored constitutes explanatory territory any adequate framework must address, not mere curiosity to be set aside. Keywords: non-ordinary experiences · cross-cultural phenomenology · anomalous cognition · transformative states · evidential scope · consciousness studies · epistemic exclusion Part of the Return to Consciousness research program — 30 philosophical essays exploring consciousness-first metaphysics.
