You may have experienced a feeling of uneasy awakening, feeling heavy on your chest, preventing you from moving, unable to move any muscle of your body, including your tongue, to scream for help from those who live with you at home.
You are awake and sure without question because you see what is around you in a natural vision room and you hear a talk from the next room, but whatever you try, you can not do from your bed and escape from this dreaded thing that stabs you from the bottom of your head to the last hairs of your head. A body like a spring !.
This case is called colloquial (or rapus). Of course, it has historically been a popular thinker, and has been interpreted as superstitious because there is an object that sits on the chest and prevents the sleeper from performing.
But, as usual, science is a tracked machine that defies all these fragile puzzles under the weight of analysis and conscious search for causes and causes.
Physically, this condition is called sleep paralysis, which occurs when breaking barriers between the world of wakefulness and sleep, may be after sleep or before, but most often after entering the state of sleep.In which the senses of hearing and vision is effective and normal to add readers fear may be The situation is accompanied by an audio or visual hallucination sometimes, which may sound sounds that do not really exist in the way they actually exist !.
Mechanism and Reason:
Sleep is divided into batches of phases oscillating between two lines called NREM and REM.
The first is the situation where dreams are not present and the second is the state of engagement in dreams. The second term here refers to the rapid eye movement and the first without this movement.
We can confidently claim that man (extra information: and even many mammalian animals) that enters the REM phase is in fact dreaming, because this random movement of the eye is actually a simulation of the eye movement that sees the viewer in dreams.
If you dream and raise your mind to see a certain scene in the sky of your dream, your eyeball will move real up !.
These two cycles rotate in several batches, each with approximately 90 minutes.
In the REM phase, a separation occurs between the brain and the voluntary muscles in general. This is because the body and its muscles do not really interact with the events in which the dreaming brain engages. Imagine if you were moving your hands and feet to actually mimic what is happening in your dreams and You are asleep, there will be a danger to you from these unconscious movements.
The question is how an evolutionary mechanism appears to be against this misfortune.
Horse Stud:
But in some cases wake up before the end of the REM stage, so find his muscles paralyzed and separated from his conscious activity and beyond the scope of control, although his hearing and vision and awareness of the environment is sound in principle !.
Therefore conscious of being self-conscious but unable to control his body.
It has been observed through studies that sleep paralysis is mostly related to sleep on the back and face to the top (note how this point increases the conviction of some of the presence of a creature lying on their chests!).
And the causes of this situation:
1 - lack of regular sleep.
2 - accumulation of pressure and anxiety.
3 - abuse hallucinations.
Preventive measures: - Follow the habits of sleep regulator - Try to reduce anxiety before sleep - Stay away from hallucinogenic drugs
And as a last advice: If you go into sleep paralysis and happen to be liberated from it, do not sleep right away, because it will come back and catch you to terrify you again.
