Dream, that's how I understand it.
Dreams are actually a mixture of things in your real life. .
It comes from your real life, but it is not exactly the same as reality.
Because when you sleep, part of your brain is active. But your brain cells, or the thinking part of your brain, are not all involved in the work, so what you see in your dream is just pieced together. These patchwork things may be deep in memory or shallow. . . Like what happened when I was a child, or what happened that day. .
Now I come back and say that I dreamed of my former lover. . . In fact, this is just a part of your brain cell. I retrieved some fragments of this memory and then mixed the contents of other parts together. . . So in your dream, you will dream about your former lover. . . You may dream that someone who is dead comes back to you, but you know that he or she is dead. . . . Because at this time, your memories of different periods are mixed together. . .
In a dream, it's actually like you're sitting in a different space-time machine. You can see you at different times, things around you at different times, or people. .
They can appear in the same scene together. . .
I wonder if you can understand what I said. . . Ha ha. ..
