He trained as a nuclear engineer, taught to trust instruments and evidence. He spent the rest of his life seeing things no instrument could record.With a foreword by Joshua Cutchin, author of Ecology of Souls.A black triangle the size of several jumbo jets crossed the night sky in silence while he stood and watched. A being stripped to the blood once appeared at his patio door. During a near-death experience, he rose into a light he did not want to leave.Kevin Cann gave seven years to the Navy's nuclear program and thirty-one more as a systems engineer. He never wanted to believe any of it. He kept seeing anyway, and finally set it all down.Autobiography of an Experiencer gathers a lifetime of these encounters, each told plainly and left standing. A closing section lays out every honest reason to doubt them, written by the author against himself. One rule holds throughout: debunk the explanation, never the experience.This is not a book of proof, and it does not ask to be believed. Jacques Vallée investigated one of its events. Jeffrey Kripal of Rice University became Kevin's friend and stood beside him on the stage at Esalen. Cutchin reads the whole book as a study in twoness, the experiencer and the explainer turning out to be the same man.The story moves through childhood terror, a late diagnosis of autism, addiction, and collapse, and arrives somewhere the hard years never promised: a contented life.For readers of UFOs, near-death experience, neurodivergence, and the far edges of human consciousness. And for anyone who has suffered and needed to know that a strange and painful life can still come out whole.
