'Sleep Language' Enables Communication in Lucid Dreams

Researchers have developed a "language" called Remmyo, which relies on specific facial muscle movements that can occur during rapid eye movement (REM) sleep. People who are capable of lucid dreaming can learn this language during their waking hours and potentially communicate while they are asleep. Remmyo consists of six sets of facial movements that can be detected by electromyography (EMG) sensors on the face. The translation software can type, vocalize, and translate Remmyo, but its effectiveness is uncertain and needs improvement.
