Does Dreaming Too Much Affect Rest?

It is common to hear people complain, "I dreamed all night and didn't get any rest," or "I had so many dreams at night that I hardly slept." So, does dreaming really interfere with rest? Is dreaming a sign that the brain hasn't rested or hasn't rested well?

This notion is incorrect. Dreaming and being able to recall dreams are not indicators of shallow sleep, nor can we say that dreaming means one hasn't slept well.

In fact, dreaming is a physiological phenomenon. Regardless of whether you remember your dreams, you are likely to dream 4 to 5 times every night.

Therefore, saying that one dreams all night or doesn't dream at all is unrealistic, and the idea of having many or few dreams is also misleading.

Research has shown that the sensation of dreaming is not necessarily linked to the severity of insomnia. In other words, the presence or intensity of dream sensations cannot serve as objective indicators of whether someone is experiencing insomnia or the degree of insomnia.

So, why do we hear such complaints? Scholars have analyzed surveys and believe they are related to the following factors:

(1) A lack of knowledge about sleep and the relationship between sleep and dreaming.

(2) The individual's emotional state.

(3) An excessive concern for one's health and an overemphasis on dream sensations, which can amplify the perception of dreaming. This, in turn, heightens worries about health and fear of insomnia, creating a vicious cycle.

(4) People are more likely to recall dream content during REM sleep and upon waking later in the night.

(5) Individual differences in functional states; different individuals experience dreams differently, and even the same individual may have varying dream sensations at different times or under different functional states. Thus, some people may feel they dream a lot during one period and less during another.

Additionally, some individuals may not experience obvious insomnia, but after dreaming at night, they feel fatigued during the day. This is often due to psychological factors. Dreamers tend to associate the content of their dreams with unpleasant feelings, which can increase mental burdens and suppress emotions, leading to various discomforts.

Dreaming itself has certain benefits for individuals and sleep. Unless you are experiencing frequent nightmares that prevent restful sleep, or if you have significant daytime sleepiness that affects your normal work and life, it is advisable to consult a doctor to identify the underlying causes and seek treatment.
