Many people may have had this feeling, that is, just fallen asleep or just woke up, feel their consciousness has been awake, can clearly feel the surrounding environment, but the body does not obey their own command, want to move can not move, want to talk and can not speak, sometimes may also be accompanied by the corresponding dream, some people even hallucinate, let people feel very scared. The common people call this condition “ghost pressure on the bed” or “ghost pressure on the body”, and in medical terms it is called sleep paralysis, a sleep-related disease. According to studies, 40% to 50% of people will experience sleeping paralysis at least once in their lifetime. How does sleep paralysis occur? We sleep in a certain cycle, with the sleep cycle being, in order, sleep onset, light sleep, mid-sleep, deep sleep, “rapid eye movement” (dreaming), and then on to the next cycle. Sleeping paralysis is mainly related to the early onset of the dreaming phase. Sleeping paralysis can occur at any age and is most common in adolescence or young adulthood. Sleeping paralysis usually occurs during the process of falling asleep or waking up. Generally, in cases of mental stress, too much anxiety, stress, overexertion, sleep deprivation, and supine sleeping position, sleep can lead to early dreaming and “ghosting” of DD sleep paralysis. There are usually no complications and everything returns to normal after the attack. In general, the disease does not require special treatment, as long as you pay attention to good habits, avoid overwork and stress, and sleep on your side if necessary to avoid recurrence. If the attacks are still frequent, they can be treated with antidepressants that have an inhibitory effect on fast-acting sleep under the guidance of a doctor.
