Why is it easy to have strange dreams? I used to sleep too much

Insomnia and dreams, I'm afraid many friends will encounter a problem. Similarly, in the eyes of foreign experts, this issue also needs to be paid enough attention. The study found that if the sleep time is too long, it is more likely to cause dreaminess. What's going on? Come and have a look.

New research has found that our dreams will become more and more strange with sleep time. This may explain why we wake up confused by our dreams.

Dreams will become more and more bizarre

Do you have such a feeling? "We found that from the first half of the night to the second half of the night, dreams become more and more bizarre."‘ Dr. Josie Malinowski of Bedford University pointed out. In the second half of the dream, what happens in the dream will become more and more complex and wonderful. Even before a person wakes up, his dream will reach a strange level that cannot happen in reality - "for example, a wild animal is wantonly destroying your back garden." Not only that, with the passage of time, dreams will become more emotional, whether they are beautiful dreams or nightmares.

Early stage of dream and daily media

Look at this interesting experiment. In the experiment, the researchers monitored the sleep of 16 volunteers by sensing their eyelids and heads. Then, the researchers woke everyone up four times in the evening and asked the volunteers to recall all the contents of the dream and talk to them about the relationship between the contents of the dream and real life the next morning. In the early stage of sleep, dreams are more related to the media content they contact in their daily life, such as a TV program or a book. Events in life appear later.

Non heterogeneous sleep nightmare

You know what? In medicine, we can divide sleep into heterogeneous sleep (people often dream during sleep, accompanied by rapid eye movement) and non heterogeneous sleep. In the non heterogeneous sleep stage, our immune system enters the state of automatic repair and enhancement. At this time, our sleep is relatively peaceful. However, physical and mental discomfort can also lead to strange dreams and even nightmares. Our sleeping brains constantly process metaphors and symbols. In the phase of heteromorphic sleep, our brain tries to grasp and process extreme feelings, and the things that annoy us are processed through the pictures we see in our sleep. "

Premenstrual syndrome leads to nightmares

Female friends should pay attention to this. Some experts believe that premenstrual syndrome leads to more nightmares. A 2008 study showed that women are more likely to have nightmares than men (30% of women surveyed said they had nightmares recently, while only 19% of men said they had) Dr Jenny Parker, a psychologist at the University of West England, pointed out that nightmares are related to changes in body temperature, which is consistent with changes in body temperature during a woman's menstrual cycle. The increase of premenstrual progesterone hormone leads to the rise of female body temperature, accompanied by insomnia. This can cause sweating, hot flashes and nightmares. "Premenstrual women's dreams are often more radical and less easy to forget." Dr Parker added.

Nightmares reflect their own diseases

You know what? Our nightmares can reflect our own physical problems, such as respiratory diseases. Foreign studies have pointed out that patients with respiratory diseases usually dream of choking water or suffocating to death; Patients who sweat too much often sweat in their sleep.

Therefore, various scenes in dreams also need our attention. It is not only a psychological hint, but also an alarm for physical diseases.
