Settings, sceneries, and landscapes from 3-HO-PCE

Settings, sceneries, and landscapes refer to the perceived environments in which the narratives and events of internal or external hallucinations take place. This effect is capable of manifesting in a seemingly infinite variety of potential places and settings, each rendered with varying degrees of detail, coherence, and immersive depth. These hallucinatory environments serve as the stage upon which autonomous entities, scenarios, and other hallucinatory content unfold, and their character profoundly shapes the emotional tone and meaning of the experience.

When explored, the geography and architecture of these settings can organize themselves as static and internally coherent — behaving like real places with consistent spatial relationships, identifiable landmarks, and navigable layouts. However, they may equally manifest as non-linear, nonsensical, and continuously morphing environments that do not obey the laws of physics or spatial logic. Rooms may lead into impossible spaces, corridors may loop back on themselves, and the landscape may shift between biomes mid-stride, creating a dreamlike quality where the rules of reality are fluid and negotiable.

The chosen locations, appearance, and style of these settings may be entirely new and previously unseen — constructed from novel combinations of visual elements that feel genuinely alien and unprecedented. However, there is often a strong influence from real-life locations stored within the person's memories, with the hallucinatory environment drawing upon, recombining, and transforming familiar places into altered versions of themselves. Childhood homes, frequently visited locations, and emotionally significant places commonly serve as raw material for these constructions.

There are numerous common themes and archetypes that recur across reports from different individuals and different substances. These include dense jungles and rainforests, vast deserts, frozen ice-scapes, sprawling alien cities, natural landscapes of impossible beauty, deep cave systems, outer space habitats, enormous architectural structures, ancient civilizations and ruins, technological utopias, organic machinescapes, underwater realms, crystalline palaces, and cosmic voids. The prevalence of certain archetypes suggests that these settings may draw from deep-seated patterns in human visual imagination and collective unconscious imagery.

Settings, sceneries, and landscapes are most commonly induced under the influence of heavy dosages of hallucinogenic compounds, particularly psychedelics such as DMT, ayahuasca, LSD, and psilocybin at breakthrough doses, as well as dissociatives such as ketamine at hole doses, and deliriants such as DPH and datura. The effect tends to emerge most fully during periods of sensory deprivation — eyes closed, in a dark and quiet environment — where external visual input is minimized and the brain's hallucinatory constructions can occupy the full visual field without competition.

The emotional character of these settings can range from breathtakingly beautiful and awe-inspiring to deeply unsettling and alien. The same individual may experience radically different environmental themes across different experiences, and the setting often seems to reflect or amplify the person's emotional state — producing paradisiacal landscapes during positive experiences and hostile, barren, or labyrinthine environments during difficult ones. This responsiveness to mood and mindset is a key reason why set and setting are considered so important in psychedelic use.
