Sleepwalking is a phenomenon where individuals engage in walking or other activities while asleep, typically during the deeper stages of non-REM sleep. It is characterized by a person getting out of bed and moving around, often with a vacant expression and limited awareness of their surroundings. Sleepwalkers may perform routine tasks or exhibit purposeless actions, sometimes even leaving the safety of their homes. The emoji sequence "🛌💤🚶‍♂️" visually represents the connection between sleep (represented by the bed and sleeping symbol) and the act of walking (symbolized by the walking man), which encapsulates the essence of sleepwalking.
