Alice's hat bears the insignia AVFC which stands for Aston Villa Football Club, the famous soccer team from writer/director Jude Rawlins' hometown of Birmingham, England. It is exactly the same hat as worn by the character Leyland in Rawlins' previous movie Little Johnny Jewel.
Rawlins and Haroldson became romantically involved during the making of Dream Time, which Rawlins admits may have subconsciously influenced aspects of the screenplay, although they had almost concluded filming when they confessed their feelings to each other.
Rawlins also cites Fellini, Bergman and John Cassavetes as major influences on his filmmaking in general, but especially on Dream Time.
The music playing in the background when Hester explains to Ronnie how she first encountered Albie is a 2006 live recording of Jude Rawlins' band Subterraneans. It is only the second time Rawlins has used Subterraneans music in one of his own films, the first time being in the experimental film Red.
The title of the film was partially inspired by the Tom Verlaine album Dreamtime, as well as songs by The Heart Throbs and The Cult. Tom Verlaine also wrote the song "Little Johnny Jewel".
