Frequent Dreaming Means Poor Sleep Quality?

Updated: Feb 18, 2019

“I often dream and rarely feel immersed sleep. Does that mean poor sleep?”

 What?No.

Frequent dream dose not mean terrible sleep state.

When does the dream appear?

After falling asleep, the brain also goes into a dormant state, but a small number of brain cells are still active, which is the basis of dreams.

The normal sleep structure cycle of humans is divided into two phases: non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM).

NREM and REM alternately appear,once called one sleep cycle, two phases of the cycle to and fro,every night one human usually can have 4 to 5 sleep cycles per night, each cycle 90 to 110 minutes.

Most people's dreams occur during REM sleep. During one night, human beings experience about 5 to 6 transitions from NREM to REM. As the NREM phase gets shorter, the REM phase gradually gets longer, this situation leads to more dreams before you wake up in the morning.

Does dreaming affect sleep quality?

Sometimes people may find that someone said, "I brokenly dreamed dreams at night and felt like I had a bad sleep quality."

This is not the case. Dreaming is a mechanism to protect sleep, an expression of desire in the subconscious mind, which is beneficial and harmless to sleep.

According to the sleep cycle, people can dream up to five times a night and the time will not exceed two hours, so they can sleep peacefully every night.

It can be said that it is not dreams affect the quality of sleep, physical or mental tightness actually affects the quality of sleep, physiological illnesses such as sleep apnea make people remember dreams and feel that they frequently dream.

For example, people did some nightmares that make themself sad when mental stress was high during the day time,the emotion of sadness or fear make people wake up from sleep;It is difficult to fall asleep again when the negative mood around, excessive fatigue leads to the decline of sleep quality.

Think day by day and dream night by night

“Think at daytime dream at night” the action is due to the fact that information during the day is constantly consolidated in the cerebral cortex, forming long-term memories.

If you dream about what happens during the day, it is actually related to the process of the cerebral cortex and the hippocampus helping the body to consolidate memory at night.The hippocampus mainly stores short-term memory, while long-term memory is more stored in the cerebral cortex. Simply put, daytime events which intermittently appear in dream are mostly related to memory storage in the brain.

Can we not dream?

Dream is indispensable physiological and psychological phenomenon of human body.The deprivation of dream is actually a forcible interruption of sleep. It will lead to a series of physiological abnormalities, such as blood pressure, pulse, body ascending temperature. At the same time, it will also cause a series of adverse psychological reactions, such as anxiety, nervousness, irritability, perceptual hallucination, memory disorder, orientation disorder and so on.

In addition, dream is a way to coordinate the balance of human mental world, and it is the expression of subconscious desire, especially the regulation of people's attention, emotion and cognitive activities.

Therefore, being able to dream is conducive to physical health and is one of the important factors to ensure the normal vitality of the body.
