I always feel that the memories in dreams are shared

As title. It is a very real feeling that the memories in dreams are shared and inherited from each other.

I don’t know if you have ever had this feeling. Sometimes when you are doing activities in the dream world, you will suddenly feel familiar with some scenes or activities. After you wake up and recall it, you will find that this memory is not reality. What happened in life is what happened in dreams. If it were not a dream, it might become a memory that I would never remember.

This is one kind of situation, and there is another kind of situation, as if I have been in a dream world for a lifetime. Yes, I have been to this place in my dream before, but I had been there several years ago in this dream, and it felt like I was out of place in time and space.

Dreams are really wonderful... (Sorry, this paragraph is a bit unclear and incoherent orz)
