The Mindscape is a plane of existence within the consciousness of a person's mind in which their thoughts, memories, and dreams all exist in one dimension-like realm. Every living individual has their own version of the Mindscape that can be accessed by them through sleep or in a comatose state. The Mindscape of others can be shared or accessed by the outside consciousnesses of others through the use of magic, telepathy, or advanced pieces of technology such as the cerebral inhibitors made by Harry Wells, A.I.'s such as Gideon is also known to be able to access the mindscape of others. It can also be accessed easily by magic users such as the Music Meister, aliens with psychic powers such as Naltorians, Green Martians, White Martians, and Dominators and meta-humans with psychic abilities like Dinah Redmond, Perenna, and Cecile Horton.
