Unthinkable

An Extraordinary Journey Through the World's Strangest Brains

IMAGINE . . . getting lost in a one-room flat; seeing auras; never forgetting a moment of your life; a permanent orchestra in your head; turning into a tiger; life as an out-of-body experience; feeling other people's pain; being convinced you are dead; becoming a different person overnight.

Join me on my journey to meet people living with the world's strangest brains.
