A Dream Machine

Dream Machines are used by the Martians of Mars to enter the Dream-World.

They were essential in saving the minds of the Martians after Raxachk had released a plague that killed their bodies. However, Raxachk himself used them millennia later to swap the minds of Martians into human bodies, leaving the human minds in the Dream-World.

In Martian Dreams the Avatar had to use these machines to return the correct minds to the correct bodies, before finally confronting Raxachk in the Dream-World, to defeat him once and for all.
