Although science has not given a definite explanation, there are still many discoveries. Almost 80% of people have experienced this phenomenon, and this phenomenon called hypnic jerk (sleep muscle spasms) occurs in people who are anxious, have poor sleep quality, and are tired. The scientific explanation for this phenomenon is that when people sleep, the muscles will be fully relaxed, and at this time, the muscles will send a signal to the brain that the muscles are relaxed, and the brain will misjudge when receiving this signal (especially in the state of exhaustion and anxiety), thinking that the body is in a state of falling (the body is also relaxed in the state of falling), and at this time the brain sends a signal to the body to make the muscles spasm to return to the upright state.
This is normal, don't worry, keep a good attitude and rest well.

This is known as "sleep cramps". It occurs when you are about to fall asleep or just after falling asleep, and because it is short-lived and does not affect your health, it is rarely used as a complaint in the hospital, and it is rarely studied in medicine. I think it may be due to the fact that some part of the brain is still excited when I first fall asleep, or that the spinal cord that has been uninhibited from the brain is in some state of excitement.
More research should be done to determine this issue, such as ambulatory electroencephalogram (EEG) or electroencephalogram (EEG). However, since it is not harmful, probably few people will be willing to undergo these tests.

When you fall asleep or are about to wake up, your limbs or whole body will twitch suddenly, and then you will wake up suddenly. This phenomenon is often referred to as "sleep initiation" and is caused by the brain misreading the natural relaxation process of muscles during the body's dreaming, and reactively causing the muscles to suddenly tense in order to control the feeling of muscle relaxation. During the day, work is tiring, and excessive exercise leads to excessive physical expenditure, excessive muscle tension, lack of calcium in the body, and occasional tics.

Generally speaking, the heart will not let you feel it when you dream, and you feel the violent beating of your heart, which means that you have some problems with blood pressure or heart, it is recommended that you go to the hospital for a physical examination, which is safer.

As the saying goes, I dream day and night, and it's normal to dream, and sometimes I often dream of a piece of water, and there are stars twinkling on the water, and then I fall from the sky, but I can't fall into the water, and then I wake up from the dream. It is estimated that this is related to the fatigue of the day or some things are not handled well, it doesn't matter, don't believe in those superstitions, relax before going to bed, and take a hot bath.

Why do I feel like I fall when I sleep? Then why do you feel like you're falling when you sleep? How can people lie down and sleep when they are sleepy?
Why do I feel like I fall when I sleep? Then why do you feel like you're falling when you sleep? If people lie down and sleep when they are sleepy, how can they have a sense of falling?

If you feel a feeling of falling, first of all, you may have a neurasthenia due to hallucinations, and it is recommended that you go to the neurology department of the hospital for examination.

Why do I feel like I fall when I sleep? Because there is tension when sleeping, sometimes if you are too nervous at work, you will feel a sense of falling.

I do it a lot, not cramps, because it doesn't hurt at all.
Especially when you are half-asleep and half-awake, not all organs of the human body have entered a state of sleep, and some organs such as legs may still be active.
However, if you feel pain when shaking involuntarily, it should be a cramp, and the main causes of cramps are:
1.Poor local circulation, peripheral vascular lesions, or varicose veins.
2.Sudden changes in ambient temperature.
3.Emotional overtension.
4. 5.Insufficient levels of minerals (e.g., magnesium, calcium) in the diet.
6.Certain chronic diseases, pregnant women also have an increased incidence of cramps.
7. 8.Motor neuron disease, spinal radiculopathy or peripheral neuropathy.
9.Certain drugs to lower blood pressure and blood lipids may also cause cramps in the feet.
10.Unknown reasons.
How to reduce the chance of cramps:
1.Pay attention to calcium supplementation: During puberty, calcium will be relatively deficient, which is more likely to cause cramps.
2.If you are prone to cramps when you sleep at night, stretch on the cramp-prone area before going to bed.
3.Keep warm when sleeping.

A feeling after dreaming, because the spinal nerves and brain are separated when you fall asleep, the human body generally does not move [except for sleepwalking], the muscles are stiff, and you naturally need to relax, so you will feel weightless and wake up from sleep.
-
There will be a normal feeling of muscle relaxation during sleep, which is transmitted to the brain, and there will be a sudden feeling of weightlessness.
-
It's normal for almost everyone to be like this, it's your brain testing whether you're alive or not, there's evidence on the Internet, it's not a joke.
-
This is normal, I do it a lot.
-
I feel that way too! It is said to be normal.

When the body is ready to go into a deep sleep, accompanied by a sudden feeling of weightlessness from a high altitude, it is actually a normal physiological phenomenon, called physiological muscle jerk, often because people in a state of tension, fatigue, etc., due to insufficient neuronal inhibition, resulting in an increase in motor neuron excitability, resulting in abnormal discharge, so that the muscles are gone.

1.If it is in the phase of growing the body, it is quite normal to dream of such dreams . 2.If you're an adult, then it's just a sign that you're too nervous or sleeping in the wrong position.

According to the principle of physics, when an object moves in a circle, a centrifugal force is generated, and the magnitude of this centrifugal force is proportional to the square of the rotational speed. Therefore, the greater the speed, the stronger the centrifugal force, when the centrifugal force and gravity are balanced, the object can rotate around the earth non-stop, so the flight speed of the artificial satellite must be large enough to balance the gravitational force, so that it can fly without stopping. >>>More
The blades of the eternal electric fan will fall off, because to a certain extent, the screws may be loose, or it is a long time ago, so the Shanzhi page falls off.
The real reason for the falling object from the sky is the attraction of the center of the earth. Since the Earth is an object with a large volume and mass, the volume and mass of an apple are negligible compared to the Earth, equivalent to a particle. Because of gravity, the apple falls towards the center of the earth. >>>More
