What does it mean to dream about maroon?
Maroon often suggests depth of feeling held in check, a dark muted red tied to richness, restraint, and old strong emotion.
Four ways to read it
Each reading below comes from a named tradition and a cited source, so you can see where it came from and decide what fits your dream.
Freud
Freud read intense colour as a carrier of strong feeling, and maroon is red darkened and quieted, perhaps desire or anger banked rather than blazing. He would ask what in waking life had stirred you and then been held back. The deepened colour suggests feeling under cover.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung saw red as the warmest colour, the hue of blood and passion, and maroon is that warmth deepened toward the earthy and the dark. It can read as mature, settled feeling, richness, and depth, or as old anger and hurt grown heavy. The dream's mood tells you which side shows.
Jungian concept (our summary).Modern
Under the continuity view, maroon often follows from a deep or serious waking mood, or thoughts of comfort, richness, and the autumnal. It may also simply echo a maroon thing from your day, wine, an old leather chair, a deep-red wall. Your own sense of the colour is the best starting point.
Continuity hypothesis (our summary).Mythological
The deep red of wine and dried blood ran through many old rites, the colour of feast and sacrifice alike, of life poured out and shared. Darkened red dressed both the honoured and the mourning in various traditions. It has long carried weight, depth, and the gravity of strong things.
