Not all cases of interrupted sleep, though, are readily apparent to the sleeper. Some people experience very brief and minor awakenings or arousals during the night without realizing it. For example, people with obstructive sleep apnea (OSA) have repeated lapses in breathing that cause brief arousals from sleep.
While your brain never truly shuts off, when you do fall asleep, your brain sends inhibitory neurons that help reduce conscious awareness to get to a point of deep sleep.
This body movement is what doctors and scientists call a hypnic (or hypnagogic) or myoclonic jerk. It's also known as a "sleep start," and it can literally startle you out of falling asleep. This type of feeling is normal, and it can happen before people enter the deeper stages of sleep.
Why You Feel Strange Sensations When You Fall Asleep (Falling Sensation, Tingling, Jerking) Some people can experience strange sensations when falling asleep, especially when the brain moves between sleep stages. If you don't know what they are, this can be a terrifying experience.

Hypnagogic sleep paralysis occurs when your body has trouble transitioning into the REM cycle (falling asleep) and hypnopompic occurs when your body has trouble transitioning out of it (waking up). Studies estimate that most people experience sleep paralysis at least once, although they may not even be aware of it.
They may involve feeling bodily distortions; feelings of weightlessness, flying or falling; and sensing the presence of another person in the room. Auditory (hearing something that's not there): About 8% to 34% of hypnogogic hallucinations are auditory — either hearing sounds or voices.
While it's true that during some sleep stages our brains pay very little attention to what's happening around us, during other stages we're able to hear and process sounds even in our sleep. Not only that, but we are listening for certain sounds while we sleep, even when we're in deep sleep.
