Most people with aphantasia do still dream, though often less vivid and less frequent than typical dreamers. Some dream in images they can't recreate while awake.

Vividness ratings robustly capture a wide range of subjective experiences, from internal mental depictions to externally projected imagery. This suggests aphantasia should be redefined to distinguish between faint imagery and a total lack of pictorial representation.

This short reply to three commentaries on a 2023 book about mental imagery restates the book's view that aphantasia is not a single condition: many people with it still dream in images or have flashbacks but cannot call up images at will, which differs from having no conscious imagery at all. Most of the reply concerns other questions, chiefly how the book's idea that imagery forms part of everyday seeing differs from predictive processing theories, and how philosophy can work with the sciences of the mind. It reports no new data.

The paper argues that two features of dreams are better explained if dreaming is a kind of imagining than if it is hallucination plus belief. Things can be true in a dream without being shown, as when a dreamer on a beach simply is an accountant, and dreams can skip across long stretches of time the way films do. Both match how people settle what their waking imaginings stand for. The paper calls its arguments supportive but not conclusive and does not claim that dreams never involve hallucinations or beliefs.

This philosophy paper uses reports that most people with aphantasia still have visual dreams to test the view that dreams are a kind of imagining. The author argues this undercuts the version in which all imagery is something we actively do, but not a version in which dreams involve passive, involuntary imagination. The paper proposes testing whether people with aphantasia can learn lucid dreaming, in which dreamers know they are dreaming and can sometimes control the dream.

Researchers distinguished between objective imagery performance and subjective conscious experience. This explains how non-imagers can successfully process visual information despite lacking a mind's eye.
