I often dream of my dead childhood playmate, of his resurrection, of talking to him, of his living parents and brothers, and often dream. Why?

This is a dream of psychological compensation, because when we grew up together, we should grow up together, but I have never experienced the experience of living and growing up together since I was an adult, and I always regret it, especially after he died, I didn't even burn paper to give him a ride. I often dream of him as a compensation for my psychological needs.

In addition, the experience of growing up together left a deep impression on your mind. These memories seem to be forgotten after many years, but they actually exist in the cerebral cortex, just like a folder you put in your computer. Although you forget where you put it and don't remember putting it in, it exists. During the day, your brain doesn't search for past memories because of daily chores, but at night, your brain doesn't fall into a deep sleep.

I suggest you drink a cup of hot milk before going to bed, and have a good hot foot to improve the quality of sleep.
