The sleep cycle means how human sleeps and at what time. For example if everyday I wake up at 7 in the morning, then take a nap at 12 at noon and go to sleep at 11 at night that is called sleep cycle.
Melatonin
The human sleep cycle repeats approximately every 90 minutes throughout the night. It consists of four stages (including REM sleep) that are cycled through multiple times. A typical adult will go through 4-6 complete sleep cycles in a night.
Stage 2 of the sleep cycle usually lasts around 10 to 25 minutes and tends to make up around 45-55% of total sleep time. It is characterized by a decrease in body temperature and heart rate, as well as the presence of sleep spindles and K-complexes on EEG readings.
No, you cannot "save up" on sleep ahead of time. It is important to maintain a consistent and adequate sleep schedule for optimal health and performance. Trying to accumulate extra sleep in advance can disrupt your body's natural sleep-wake cycle.
The reticular formation is located in the portion of the brainstem known as the pons. Its functions are primarily that of regulating the sleep/wake cycle, and assist in the function of discriminating incoming stimuli (which could impact the sleep/wake cycle, as well).
REM sleep is important because this it the stage of sleep helps our brains develop.
REM
Sleep apnea is a serious sleep disorder that occurs when a person's cycle of breathing is interrupted during sleep. Untreated sleep apnea can disrupt the sleep cycle hundreds of times a night.
REM or Rapid Eye Movement. You sleep in cycles, moving from lighter to deeper sleep and back. A sleep cycle lasts about 90 minutes, with REM occurring toward the end of each cycle. The REM stage gets a little longer in each cycle; you may only dream for a few seconds in the first sleep cycle, and for a large percentage of the last cycle of the night.

True
The longest REM cycle occurs in the early morning hours. This is why it's easier to lucid dream on weekends, longer hours of sleep in the morning.
Yes, the dreaming cycle of sleep comes in the deepest part, so that means you're getting a full cycle, or a good night's sleep.
NO
yes
