Why do I always have nightmares? For example, in the last five years, I have often been awakened by ghost dreams, and I have often dreamed of snakes these days. When I woke up, I immediately felt a snake enter my body. Nightmare is a kind of fear caused by the fast and slow heartbeat when people sleep.

Among them, too fast heartbeat will cause nightmares of being chased; Bradycardia or premature beats can cause people to have nightmares of hanging and falling.

Aristotle, an ancient Greek scientist, predicted that nightmares are likely to be a harbinger of disease. Ringo, a famous doctor in ancient Rome, recorded such a thing in his works: a person often dreamed that his left leg was as heavy as a stone and could not walk. Soon, his left leg was paralyzed.

Some modern physiologists, psychologists and medical scientists are also constantly exploring the relationship between nightmares and diseases. According to their research, always dreaming of terrible animals such as spiders and poisonous snakes is often a sign that the skin will break; If you repeatedly dream of being chased, falling off a cliff and want to shout but can't, you should pay attention to the pathological changes of your heart; Often dream of brain compression and dyspnea, pay attention to lung diseases; Rotten foods such as rotten fish and shrimp are often found in dream of eating, which may be a harbinger of gastrointestinal diseases.

Why do these nightmares become a harbinger of disease? Because in the early stage of the disease, although the patient has not yet noticed it, latent lesions have already appeared in the body. During the day, when people wake up, a large number of external stimulus signals are introduced into the brain. At this time, the brain is busy processing external information. In contrast, the weak stimulus information in the early stage of onset is "insignificant". In addition, the brain has the function of adjusting and adapting to this mild symptom, so the human body has no feeling.

However, when you sleep at night, the situation is very different. At this time, many cells in the brain have entered a "rest" state, and many strong external stimulus signals have been unable to enter the brain, and the function of coordination and adaptation has been greatly reduced. Therefore, abnormal signals of latent lesions in the body can activate cells in the corresponding parts of the brain. At this time, the nightmare appeared. Because some nightmare scenes are related to latent lesions in the body, they may become symptoms of disease.

Speaking of this, some people may be nervous: they think they are ill when they have nightmares. It should be said that this is unnecessary. However, if similar nightmares appear one after another, we should look for reasons from both physical and mental aspects in order to eliminate hidden dangers as soon as possible.

1, dream that people or monsters hit you on the head, or fill your five senses with liquid. Tip: You may have brain tumor and nervous system diseases.

I heard a strange sound in my dream. It is suggested that there may be some pathological changes in auditory pathway or arteriosclerosis nearby.

3, dreaming that the trachea is stuck, breathing is not smooth, and suffocation. It is suggested that there may be pathological changes in the respiratory system.

4. Being chased in the dream, I am afraid, I can't scream, I can't run. I woke up with a lingering fear, sweating profusely and my heart racing. Hint: It may be that the coronary artery of the heart is short of blood supply.

5, walking in a dream is unstable, the body is twisted, the limbs are heavy, and there is a sense of suffocation, which will suddenly wake up. Hint: It may be a precursor of angina pectoris.

I dream of falling from a height, but I always wake up before landing. Tip: It may be a harbinger of heart disease, and children with long bodies often have such dreams.

7. Dreaming of a fire scene, such as being burned by yourself. Tip: You may have high blood pressure.

8. Dreaming of water scenes, such as floods, swamps and drowning. It is suggested that there may be lesions in hepatobiliary system and kidney.

9. Dreaming of flying scenes. Tip: There may be pathological changes in the circulatory system.

10, dreaming of evil-looking people. It is suggested that there may be pathological changes in digestive system.

1 1. I was beaten in my dream and felt pain in my dream after I woke up. It is suggested that there may be latent lesions in the corresponding organs.

12, eating strange food in my dream, and smelling in my mouth after waking up; Or feel hungry in the dream, eat a lot of things, and feel very painful after waking up. Tip: There may be diseases in the gastrointestinal tract.

Eating a few slices of bread before going to bed can prevent nightmares.

When blood sugar is too low, people will feel tired, tired, irritable and unresponsive. The study also found that hypoglycemia may occur after falling asleep, making it easy for people to wake up screaming in nightmares and sweating all over, making it difficult to fall asleep again.

Why is hypoglycemia related to nightmares? Experimental studies have confirmed that people will alternate between fast-wave sleep and slow-wave sleep during sleep.

Fast wave sleep, also known as "dream sleep", is when people dream. Studies have shown that during fast-wave sleep, people's nerve excitability increases and protein synthesis in the brain accelerates. When blood sugar is too low, brain energy supply is insufficient, and protein synthesis is blocked, which will lead to prolonged fast wave sleep time. At this time, the nerve excitability will increase, and you may have nightmares at any time. On the other hand, when blood sugar is normal, protein's anabolism and energy supply are in a normal physiological state during sleep. Fast-wave sleep and slow-wave sleep are carried out alternately and orderly, and the nervous system will not be overly excited and it is not easy to have nightmares.

Carbohydrate foods can correct hypoglycemia. If you often have nightmares, try eating a few slices of bread or two biscuits or drinking a glass of milk with sugar before going to bed. This may help you reduce nightmares and improve the quality of sleep.
