REM sleep usually occurs in cycles during the last 5-6 hours of an 8-hour night's sleep. So how much sleep we get in this stage will depend on how much sleep we get for the night. During REM sleep, eye movements increase, heart rate increases, and the normal body processes also increase. It's during this stage that dreams occur, and it's also this stage that we're most likely to wake up in the morning (feeling refreshed). These REM periods last approximately 20 minutes and can occur between 4 and 6 times per a good night sleep. Unlike the non-REM stages, our major muscle groups don't move, so we won't sleepwalk or "jar" ourselves awake during REM sleep.
There are different types of sleeps associated with the sleep cycle. It is important to get a full cycle of REM sleep. REM sleep involves active dreaming. People sometimes have up to five cycles of REM nightly.

What is REM rebound?
When a person has been deprived of REM sleep for long enough they will not cycle through sleep patterns as a well rested person would. These REM deprived patients will enter REM sleep much more rapidly and will spend more time in REM sleep over the course of the night as their body attempts to "catch up" for the lost REM. This expedited process of entering REM is called REM rebound.
If you did not get enough sleep the night before you may?
have more rem sleep than normal
How tiring is REM sleep and how much time do you spend in it?
In reality, REM sleep involves a mix of activity (bursts of eye movement and brain activity similar to alpha waves) and inactivity (body paralysis as the brain stem prevents cortex activity from reaching the rest of the body). This activity-paralysis mix gives REM sleep its other name: paradoxical sleep. Adults tend to spend about 20 to 25 percent of an average night in REM sleep. A person would be more likely to be exhausted by too little REM sleep than by too much.

Is rem sleep deep?
3/13/2012 jhh: REM sleep is NOT deep sleep. In fact, it is the lightest stage of sleep. In order from awake to deep sleep: AWAKE, REM, LIGHT, DEEP. Deep sleep and REM sleep are the most important stages though. Light sleep doesn't do much for you. Deep replenishes your body, while REM replenishes your mind. Older answer (not accurate): Yes. It is the deeper form of sleep that we experience during our sleep cycle, rem sleep is where dreaming occurs But not the deepest sleep, which would be delta. That's where, unless your a mother and hear your baby cry, you are oblivious to your environment.

Does REM occur in sleep panic patients?
REM sleep is our restorative sleep. We all need it to restore our bodies. Patients with Sleep Apnea often have a decrease in the amount of REM sleep they get but still go into REM as does everyone. You may not achieve REM every time you sleep especially when you are just taking a short nap. There may be nights that a Sleep apnea patient does not achieve REM but that does NOT mean they never have REM sleep. When someone who has Sleep Apnea achieves Rem stage the apnea events increase because the tension and mucsles relax causing the obstruction in the airway to get worse. In turn the body reacts to the lack of air by gasping, choking, moving until the obstruction releases long enough for the person to breathe again. This often brings the person out of REM stage and into a lighter stage of sleep or wake stage. Therefore REM is often reduced. Around 20% of our total sleep time a night in REM is consider normal. Most sleep apnea patients' Rem is considerably less than this.
