Army assessment of the Monroe 'Gateway Process'
A 1983 Army intelligence analysis tried to explain, in physics terms, the Monroe Institute's sound-based meditation for altered states.

The account
Lt. Col. Wayne McDonnell's report on the 'Gateway Experience', developed by radio executive Robert Monroe, speculated about consciousness, holograms and time. Released through the CIA reading room, it went viral online decades later. A magazine feature filed in the CIA's Stargate collection describes the Monroe Institute's weekend 'M-5000' workshop, in which participants lie in sleeping bags with stereo headphones while Monroe's instructions are combined with audio pulsing, aiming to hold the threshold between waking and sleep as a 'gateway' (p.2). It is a popular article, not the 1983 Army assessment.
The sceptical view
It's one officer's speculative analysis, not a finding that the technique works, and its physics is unorthodox at best.
