Quizplus · Accepted Answer

Gisela was most likely in REM (Rapid Eye Movement) sleep, which is the sleep stage associated with vivid dreaming. During REM sleep, the brain is very active, and dreams are most vivid, but the body's muscles are very relaxed, almost to the point of paralysis, which helps prevent people from acting out their dreams. People awakened during REM sleep often report vivid dreams.
