The causes of insomnia and dreaminess are complicated, both social and personal factors, which can be the result of normal aging or caused by disease factors, such as hypertension, diabetes, stroke and other diseases; bad sleep habits such as drinking strong tea, smoking and doing strenuous activities before bedtime; and congenital withdrawn and sentimental personality.
In addition, when large changes occur in society and family, it is more likely to affect the psyche and affect sleep, thus leading to insomnia and dreaminess.
