Dream content analysis in persons with an autism spectrum disorder.

Daoust et al. (2008) asked the adults with autism and 26 typical adults to keep dream diaries.

Each morning for two weeks they wrote what they remembered. The team counted words, emotions, characters, and settings.

Adults with autism recalled fewer dreams. When they did, the stories were shorter and held less detail.

They named fewer people, places, or feelings than the control group.

The result lines up with Stancliffe et al. (2007) and Eugenia Gras et al. (2003), who also saw weaker free recall in ASD adults even after training.

It looks like the opposite of Kemner et al. (2008), who found adults with PDD were faster at visual search. The tasks differ: one asks for rich inner stories, the other for quick target spotting.

Together the papers show a split: basic perception can be sharp, but turning inner experience into words stays hard.

When you ask clients about dreams, night events, or private thoughts, expect shorter answers. Don’t assume no interest—provide visual cues or sentence starters to help them share. This small change can improve your sleep interviews and rapport.
