John Deacon uses hynosis to research altered states of consciousness. One of his subjects, Michael Peacocke, is unusually susceptible and in their fist session together he recalls a Close Encounter. Deacon is sceptical of UFOs and dismisses the story as an adolescent sexual fantasy. But then inexplicable things happen and Deacon is forced to reconsider. Could UFOs be symbols projected from the collective unconscious? Are they messages from the biomatrix? Does the mind have the ability to project tulpas, objects and people which are physically real yet somehow illusory?
