Psychoplasm was a material from which artificial micro-universes known as psychoscapes could be created, including the Dalek-scapes of the Dalek Dome. If the psychoplasmic constructs within a psychoscape left the scape's dedicated chamber within the Dome, as demonstrated when the Fourteenth Doctor's TARDIS transferred them out, then the psychoplasm would begin to melt, as the material could not survive beyond the dome for long.
When the Daleks of the Golden City Zone discovered their nature as simulacra, they took control of the Dome and began construction of a quantum-powered reality gate to enter the real world. To bring through his entire Dalek Fleet, the Golden Emperor ordered the other Dalek-scapes broken down into psychoplasm as raw material. When the Fourteenth Doctor collapsed the reality gate, all Dalek constructs that had made it to the real world melted into psychoplasm. He later discovered that the Jules Rimet Trophy from the Earth Invasion Zone had also melted over his console; the Doctor worried that it had jammed the fast return switch, which, with the Dome now destroyed, would cause the TARDIS to sent him to the real Skaro to compensate, (COMIC: Liberation of the Daleks [+]Loading...["Liberation of the Daleks (comic story)"]) as, indeed, it did.

Behind the scenes[[edit] | [edit source]]
The term "psychoplasm" originated in the 19th century as a synonym for the more common "ectoplasm". Rather than this original meaning, psychoplasm's use in Liberation of the Daleks [+]Loading...["Liberation of the Daleks (comic story)"] as a substance which can be moulded into artificial worlds based on a subject's memories or dreams closely echoes the portrayal of psychoplasm in Reflections, a Spawn comic story written by Grant Morrison, where psychoplasm stolen from Hell (out of which it is supposedly constructed) was used in a secret government project to create an idealised replica of the main character's early life.
