What are the reasons why old people often have strange dreams?

Jianyi Hualin's health consultant answers for you: Don't worry, the elderly are weak and lack of qi and blood, so they are easy to dream, and some nerves are excited, which will also cause dreams. I suggest you care more about the elderly, chat with them and take a walk. Listening to the old man's psychological words, the nutrition is mainly light and soothing!
