Why is the scene in the dream easy to forget?

I think it is because people are not awake when dreaming, and their nerves are in a dormant state, so it is difficult to remember dreams after waking up.

Dreams are things that happen to anyone. They are simple, but unusual. At present, human scientists do not fully know how to realize their dreams. Our country has been studying dreams for a long time, thinking that dreams can predict what will happen in reality. One of the most famous is the dream of Duke Zhou. In our opinion, this book is groundless and even considered superstitious. But coincidence can cause some of these things to be completed, which is why people still believe this.

In addition, you will find that it is easy for humans to forget their dreams. Sometimes we will fall into a dream, and we can clearly understand and remember the details of the dream, but after waking up, we can try to rethink. Will soon be forgotten. How did this happen? Scientists have found that the memories of these dreams may have been intentionally erased, and it is your brain that erases these memories.

A recent article in Nature explains this. In order to study the relationship between dreams and memories, the Japanese research team studied a special neuron. These neurons secrete a substance called MCH, which can stimulate appetite and regulate sleep. The researchers found that this neuron may affect the hippocampus related to brain memory. After repeated experiments in mice, it was found that these neurons were activated in the rapid eye movement stage of step-, releasing MCH to inhibit memory. After further research, I finally found that the brain began to inhibit the generation of memories in the development stage of dreams. Therefore, it is easy for you to forget the scene in your dream.

Why does the brain produce such a mechanism? Researchers still don't know why. But they may think that what happened in their dreams is not that important, so they will take the initiative to forget it to reduce the burden on their brains and save storage space. Look, do many people think that the brain is their idea? Most of us think that what happens in our dreams will be better. I'll be happy to remember those things. Sometimes I forget them on purpose.
