What are the causes of poor sleep and frequent dreaming?

Generally, poor sleep with frequent dreams may be related to factors such as prolonged rapid eye movement (REM) sleep phase, excessive psychological pressure, anxiety disorders, neurasthenia, and obstructive sleep apnea hypopnea syndrome. It is recommended to seek timely medical consultation and follow the guidance of a physician regarding treatments such as general therapy or medication. Detailed explanations are as follows:

1. Prolonged REM Sleep Phase

REM sleep is a stage within the sleep cycle during which brain activity increases, eyes move rapidly, and dreaming may occur. If the REM phase is prolonged, it may lead to more frequent dreaming, thereby affecting sleep quality. It is recommended to maintain a regular sleep schedule, avoid excessive excitement or tension before bedtime, and reduce intake of stimulants such as caffeine, which may help shorten the REM sleep phase.

2. Excessive Psychological Pressure

Excessive psychological stress can cause nervous system tension, affecting the sleep process and making the brain more active during REM sleep, thus producing more dreams. Learning to relieve stress through relaxation techniques such as deep breathing, meditation, and yoga, as well as seeking social support and psychological counseling, can help reduce psychological pressure and improve sleep quality.

3. Anxiety Disorders

Anxiety disorders are caused by multiple factors, including genetic, environmental, and psychosocial factors. Patients often exhibit excessive worry and fear about daily matters, which may lead to abnormal brain activity during the REM sleep phase, resulting in more frequent dreams and impaired sleep quality. Symptoms such as anxiety, tension, and restlessness may also be present. Under a doctor's guidance, medications such as sertraline hydrochloride capsules, olanzapine-fluoxetine capsules, or venlafaxine hydrochloride sustained-release capsules may be used for symptom relief.

4. Neurasthenia

Neurasthenia typically results from prolonged mental stress and tension, manifesting as easy mental excitation and rapid mental fatigue. The cerebral cortex function may be impaired, leading to abnormal REM sleep and frequent dreaming, which causes poor sleep. Symptoms may also include inattention and memory decline. Patients may take medications such as zolpidem tartrate tablets, zopiclone tablets, or zaleplon tablets under medical advice.

5. Obstructive Sleep Apnea Hypopnea Syndrome

Obstructive sleep apnea hypopnea syndrome is usually caused by upper airway obstruction, such as enlarged tonsils or posterior displacement of the base of the tongue. Hypoxia and hypoventilation caused by the obstruction may affect the quality of REM sleep, leading to increased dreaming and reduced sleep quality. Symptoms such as snoring and apnea during sleep may also occur. Patients may follow medical instructions to use medications such as estazolam tablets, xiangju capsules, or tongqiao biyan tablets for treatment.

Establishing good sleep hygiene habits, such as maintaining a comfortable sleep environment and avoiding caffeine intake at night, can help improve sleep quality.
