Demystify REM motor atonia. Learn how glycine and GABA temporarily paralyze skeletal muscles, and either smoothly wake up or launch directly into a vivid lucid flight.
π¬ The Neurobiology Behind It:
During REM sleep, brainstem neurons release glycine and GABA to inhibit post-synaptic alpha motor neurons. This is a vital evolutionary safety mechanism called REM Atoniaβit prevents you from physically sleepwalking or acting out dreams.
Crucially: Your heart, lungs, and eye muscles are NEVER paralyzed! Any chest pressure is caused by autonomic breathing rhythms, not physical restriction.
