This is a dream I often had when I was a child.
It shows that your metabolism is vigorous, you should be a young man, your bones are developing, and you can make all kinds of movements with your dreams, such as jumping, flying, running and crawling. The process of human growth is carried out in such a dream.
It is suggested to keep quiet, read books, listen to soothing music and drink a glass of warm milk before going to bed. Don't fall asleep after exercise or when you are particularly excited. Generally no problem.
