Quizplus · Accepted Answer

REM (rapid eye movement) sleep is also known as Stage 5 sleep, and it is during this stage that most of our vivid and memorable dreams occur. NREM (non-rapid eye movement) sleep occurs during the other four stages of the sleep cycle and is generally characterized by calmer brain activity and fewer dreams. Hypnogogia refers to the transitional state between wakefulness and sleep, and AREM is not a recognized term in sleep science.
