During what cycle of sleep does the body do most of its energy restoration?
The most restorative stage of sleep is NREM-3.In a sleep cycle you progress through the stages:Initial sleep induction: NREM-1 -> NREM-2 -> NREM-3Full sleep cycle: NREM-3 -> NREM-2 -> NREM-1 -> REM -> NREM-1 -> NREM-2 -> NREM-3.A full sleep cycle takes approximately 90 minutes, but the time you spend in each stage changes during the night. At first you spend more time in stage 3, but as your body rests it will spend more and more time in REM.
Can you dream in non rem sleep?
Yes, it is possible to experience dreams during non-REM (NREM) sleep, although they are typically less vivid and less memorable than those that occur during REM sleep. NREM sleep consists of different stages, and dreaming may happen primarily during the lighter stages of sleep. However, most vivid and narrative-driven dreams are associated with REM sleep.
Can there be sleep spindles in rem sleep?
Sleep spindles primarily occur during non-REM (NREM) sleep, particularly in NREM stage 2. They are characterized by bursts of oscillatory brain activity and are thought to play a role in memory consolidation and sleep regulation. While REM sleep is associated with different brain wave patterns, it is generally not associated with the presence of sleep spindles. Thus, sleep spindles are not typically found during REM sleep.

These stages cycle throughout the night, typically repeating several times.

rapid eyes movement (REM) and non rapid eyes movement (NREM)
What is non-rapid eye movement sleep?
Non-rapid eye movement (NREM) sleep-- A type of sleep that differs from rapid eye movement (REM) sleep. The four stages of NREM sleep account for 75-80% of total sleeping time.
