Quizplus · Accepted Answer

Millie's arm and leg motions during sleep indicate that she is physically acting out her dream, which is characteristic of REM behavior disorder, a sleep disorder in which muscles remain active during REM sleep leading to physically acting out dreams. Jet lag and sleep apnea would not cause this kind of behavior, and it is not normal to physically move around in bed during a dream.
