During this phase of sleep, most people will experience muscle atonia, or being paralyzed during sleep, in which the body has effectively shut down. People with RBD do not experience muscle atonia during REM sleep, which accounts for their ability to perform physical actions during this stage of sleep. REM sleep typically takes 1 to 1 ½ hours to set in, so episodes of RBD will not commence until this time has elapsed. Some people may have multiple episodes during a night, and others may only experience them once every week or longer.
