A deep dive into one of the most widely reported mysteries of the mind—both the scientific and paranormal theories—from the authors of The Grid.

You feel like you’ve done something before . . . even as you do it for the very first time.

You engage in a conversation and suddenly realize you’ve spoken those same words before . . . to the very same person. Yet you’re positive it’s the first time you’ve ever met.

Déjà vu is the eerie sensation of “remembering” an experience or situation that never occurred. Scientific research into déjà vu has revealed intriguing theories, ranging from short-term memory misfires to neurophysiological disorders. Yet other theories suggest more paranormal causes for déjà vu, such as glimpses into parallel realities. Perhaps the true explanation lies somewhere in between.

But déjà vu is only one of the many mysteries of the mind. The Déjà Vu Enigma also explores:Memory lapses, missing time, and fugue statesThe brain as both receiver and transmitter of realityAltered states of perception and consciousness, from hallucinations to religious visionsContagious thought, curses, demonic possession, and mass hysteriaDream states, lucid dreaming, and precognitive dreamsThe Grid and parallel universes as travel routes for mind trips, brain flips, and time slips

Come journey through a world as vast and uncharted as the Cosmos. A journey through the Inner Universe—the human mind.
