Sleep paralysis is a feeling of being conscious but unable to move. It occurs when a person passes between stages of wakefulness and sleep. During these transitions, you may be unable to move or speak for a few seconds up to a few minutes. Some people may also feel pressure or a sense of choking.

What sleep inertia feels like?
You probably know the feeling all too well — grogginess that seems to weigh you down when you wake from sleep. That heavy feeling right after you wake up is called sleep inertia. You feel tired, maybe a little disoriented, and not quite fully ready to hit the ground running. It can affect anyone.
Are you more tired if you wake up during REM?

Is dreaming a sign of good sleep?
Dreaming is a normal part of healthy sleep. Good sleep has been connected to better cognitive function and emotional health, and studies have also linked dreams to effective thinking, memory, and emotional processing.
Is 1 hour deep sleep OK?
Scientists agree that sleep is essential to health, and while stages 1 to 4 and REM sleep are all important, deep sleep is the most essential of all for feeling rested and staying healthy. The average healthy adult gets roughly 1 to 2 hours of deep sleep per 8 hours of nightly sleep.
How much sleep do you need per night?
National Sleep Foundation guidelines1 advise that healthy adults need between 7 and 9 hours of sleep per night.
Should I wake up during REM sleep?
This is the rapid-eye-movement (REM) stage of sleep. Most of your dreaming occurs during this time. Again, make sure you are not awoken during this stage because you will likely feel disoriented.
Are there 5 stages of sleep?
There are five stages of sleep during the sleep cycle. Scientists categorized the stages of sleep based on the characteristics of the brain and body during sleep. Stage 1,2,3, and 4, are categorized as ‘non-REM sleep’, and the fifth stage, is REM sleep.
Can you live without REM sleep?
“There’s no evidence that REM sleep deprivation by itself will kill anyone,” Dr. Jerome Siegel, professor of psychiatry at UCLA, told LiveScience. REM sleep is characterized by heightened brain activity and is the state when dreams are at their most intense.
Why is my REM sleep so high?
What Does a Lot of REM Sleep Mean? Getting an unusually large amount of REM sleep in a given night is often an indication that you are sleep deprived. Your body routinely gets most of its REM sleep later in the night, during the final hours that you are asleep.
Is it better to wake up during REM or light sleep?
Over more cycles, the NREM stages get lighter, and the REM stages get longer. Ideally, the body will pass through four to five of these cycles each night. Waking up at the end of the cycle, when sleep is lightest, may be best to help the person wake feeling more rested and ready to start the day.
Why do I wake up at 3am?
If you wake up at 3 a.m. or another time and can’t fall right back asleep, it may be for several reasons. These include lighter sleep cycles, stress, or underlying health conditions. Your 3 a.m. awakenings may occur infrequently and be nothing serious, but regular nights like this could be a sign of insomnia.
Is Dreaming good for your brain?
Dreaming may help depression Rats deprived of that precious REM sleep for four days produce fewer nerve cells in the hippocampus, the brain’s memory center. Among humans, dreaming may also help alleviate depression.
What happens when you wake up in REM sleep?
Sleep inertia is the result of sudden awakening during REM sleep. When you wake up during REM, you still have high levels of melatonin, causing sleepiness. The longer you sleep, the higher level of melatonin is observed during REM stage.
What is the deepest sleep stage?
In the deepest level of sleep, stage IV sleep, the predominant EEG activity consists of low frequency (1–4 Hz), high-amplitude fluctuations called delta waves, the characteristic slow waves for which this phase of sleep is named. The entire sequence from drowsiness to deep stage IV sleep usually takes about an hour.
