Always dreaming of a place, a very vague concept.

The brain is actually a very complicated organ. The main function of dreams is memory reorganization. We accept all kinds of information during the day and sleep at night, just like a computer needs to deal with useless information on a disk and then delete it. In this process, we will dream, that is to say, when you dream, you will continue to think logically in daily life, and there will be hints, such as "Will you fall" when you are in the air?
