Aphantasia and Psychedelics
Experiences of aphantasia—an inability or marked difficulty in forming mental images—vary widely, and many people only discover it when confronted with how vividly others can “see” in their mind’s eye. Commenters compare inner imagery across a spectrum from total blankness to hyper-detailed visualization, explore how dreaming and psychedelics (especially DMT) can temporarily “open” visual experience, and debate whether this reflects different neural systems or just language and introspection. The thread also raises ethical and practical questions about attempts to “fix” aphantasia through meditation, training, or drugs, with some viewing it as a deficit and others as a cognitive advantage that reduces distraction.
Psychedelics and aphantasia: what people report
- Several self-identified aphantasics say psychedelics do produce visuals, but often as overlays on real perception: textures “breathing,” colors shifting, fractal patterns, faces emerging from bark or clouds.
- Others report that only very strong doses or specific substances (notably DMT, sometimes LSD+DXM) give them vivid open-eye visuals; 2C‑B, psilocybin, and mescaline are described as weaker or mainly pattern‑based.
- A few say most drugs (mushrooms, THC, opiates, even morphine) barely affect perception or headspace, often noting neurodivergence or unusually high required doses.
- Multiple commenters stress that psychedelic visuals feel different from imagination: they alter the actual visual field, rather than appearing in a separate “inner screen.”
Dreams, hypnagogia, meditation
- Many aphantasics report vivid visual dreams despite no waking imagery, suggesting different neural circuits for dreaming vs. voluntary imagery.
- Some only experience clear imagery while falling asleep (hypnagogia) or occasionally during deep meditation; these moments are described as astonishingly vivid and qualitatively unlike normal “thinking.”
- One person links meditation aimed at improving imagery with triggering ocular migraines, reducing their motivation to push further.
What counts as imagery? Conceptual vs. visual
- A recurring theme: people who “see nothing” can still describe scenes, rotate 3D objects, design, draw, or solve spatial problems using non‑visual, conceptual representations.
- Several note they “know” the house, bike, or apple without any picture—like wireframe or abstract layout—raising doubts about simple “can you see an apple?” tests.
- Others describe very faint, short‑lived flashes or outlines, or imagery that only fills in details “on demand.”
Testing and defining aphantasia
- Proposed tests include the “apple scale” and an imagined room/ball/table scenario, with follow‑up questions about details.
- Critics argue these are vulnerable to post‑hoc confabulation, overclaiming, and language differences; meta‑ignorance and witness‑testimony analogies are raised.
- There is mention of brain‑imaging work and twin case studies, but interpretation remains contested.
Ethics and desirability of “fixing” it
- Some see aphantasia as a “superpower” for conceptual focus and minimal distraction, and dislike framing it as a deficit.
- Ethical concerns: pathologizing diversity; unknown emotional impact of suddenly gaining imagery; possible links between extreme imagery and psychiatric risk; and cognitive “enhancement” implications.
- Training methods like “image streaming” are mentioned, alongside cautions (e.g., eye‑rubbing risks).
Skepticism and meta‑debate
- A significant minority suspects aphantasia is overdiagnosed, fad‑driven, or largely linguistic confusion about what “see” means.
- Others, including people who lost imagery after surgery or have experienced both states, insist the difference is stark and not just semantics.
- Both sides agree that introspective reports are the only current window into these experiences, making the topic inherently hard to settle.
