First, Freud had a book, The Interpretation of Dreams. The core theory is that dreams reflect the daily needs of individuals. So it seems that you really want to gain higher knowledge, but you also have a big problem. After hard work, you want to break through, and this strong desire to break through is reflected in your dreams.

Second, Xu Wenbing has a book "Dreams and Health", the core theory is that dreams are the reflection of the human body. Maybe your brain is too nervous and you have a nervous breakdown.

Third, if you want to dig out these memories, you must first adjust your nervous system, then you can clearly recall the whole dream, and finally restore the contents of the dream to paper or computer.

I wish you success!
