Dream Dimension

Alternate Universes[]

Earth-9047 (the Humorverse)[]

The Living Nighty-Nightmare shared his home dimension with ugly beings, thus the location itself is called the Dimension of the Great Unshowered Ones, Realm of the Living Nighty-Nightmare.^[18]

Earth-96173[]

The dream dimension was known as the lower astral planes. Human dreamers visit this harmless dimension, within and beyond the material plane. However, a powerful sorcerer like Morgan le Fay can trap humans in the dream dimension and send them to the dangerous higher astral planes, from which they could not escape by themselves. When she ensnared college student Clea Lake that way, Lake fell into a coma until she was mystically rescued by Doctor Strange.^[19]

Earth-700029[]

• Nightmare World^[4][5]
• Possibly kingdoms Anesthesia and Coma.^[17]

• Dwellers of the Dream Dimension
  • Nightmare
• Unnamed creatures (possibly H.P. Lovecraft's moon-beasts)
• Demon Bear^[21]
• Dream Denizens
  • The Ruckus

• Nightmare World and/or the Dimension of Dreams was told to be a Dark Dimension by Nightmare himself.^[22]
• Other instances of manifestation of human subconscious exist, including Otherworld, the subconscious of the British Isles^[23] (or at least its geography is, in part, shaped by the British subconscious).^[24]
• In the Dream World, all of time acts at once. This allowed Daydream to exist in the Nightmare Dimension prior to her conception on Earth.^[8]
• Any three dimensional visual representation of the Dream Dimension is necessarily distorted or incomplete,^[25] as this reality transcends the usual 3D perception of time and space.^[26] It was also described as limitless by Doctor Strange.^[27] Nightmare's Dream Dimension resides beyond all the pocket dimensions,^[25] thus being virtually infinite. However, although incredibly large, the realm was portrayed as having defined boundaries.^[28]
• Nightmare has implied he is an experient adept in manipulating the Dream Dimension, rather than personifying it. He also stated that it is required a lifetime's experience to alter reality in the Dream Dimension, establishing that conscious effort is a necessary element. He declared that Spider-Man would have to expend time learning to shape reality in order to amplify his power and exceed Hulk's, who at that time was a completely irrational beast.^[28]
