Duke Zhou dreamed that someone else had a period and changed sanitary napkins in my bed.

Dreaming is a normal physiological phenomenon. Dreaming is closely related to short deep sleep period, insufficient sleep depth and poor sleep quality. Between half an hour before going to bed and 1 hour, it is not advisable to think or read. Appropriate physical activities (such as walking) should be carried out to avoid nervous mental activities. You can also eat some foods to prevent insomnia, such as milk and fruits (apples, bananas, pears, etc. ), sugar water, millet porridge, jujube porridge, lotus seed porridge and so on. Don't use hypnotic and sedative drugs easily.
