As a narrator of his (often terrifying) dreams, Dion adopted various personas but frequently established a fey, argumentative, insolent approach to the subject at hand – be it a hot air balloon trip to the moon with a group of multi-ethnic children, a frantic journey around New York, or a tattooing job on a woman's tongue.
Critic Joslyn Layne writes that "Despite his lack of success as a song lyricist, McGregor's narration of his vivid dreamlife provided a more unique artistic contribution than any usually recorded.
A third album, The Further Somniloquies of Dion McGregor: More Outrageous Recordings of the World's Most Renowned Sleeptalker was assembled by Toronto poet Steve Venright and released in August 2004 on the Torpor Vigil Industries label.

In 2017 Verena Paravel and Lucien Castaing-Taylor made an experimental documentary film about McGregor's dreams called Somniloquies.
