Sarah wasn't expecting to experience paralysis at 7 am on a weekday during a meditation at her home. But in August, while listening to "The Gateway Tapes"a set of guided meditations intended to help people reach new planes of consciousness"she says her limbs froze. Sarah ... says the tapes"which she had been listening to on and off for months"took her on a roller-coaster journey of out-of-body experiences. "I was in and out of time and space," she says. Developed by radio broadcasting executive Robert Monroe, the Gateway Process claims to be "a voyage of self-discovery" that can help people go "farther, deeper and faster into different dimensions of consciousness." Monroe founded the Monroe Institute in 1971. The facility claims to help coax people out of their bodies via in-person and virtual retreats, and even Spotify playlists, by way of self-hypnosis style exercises powered by "binaural beats""sounds attuned to different frequencies which play in each headphone ear. In the early 1980s ... the CIA and the Department of Defense sent US Army lieutenant Colonel Wayne McDonnell to the institute to ascertain its suitability as a defense contractor. McDonnell gave the organization and its unusual curriculum his approval in a 1983 report which has since been declassified. "There is a sound and rational basis," McDonnell writes, "in terms of physical science parameters for considering Gateway to be plausible in terms of its essential objectives."
