1: Have the same dream for several days (more than 3 days).
2. Two or more dreams can be connected end to end.
Most unrealistic dreams can control themselves from waking up as long as they know that they are dreaming, as long as there is no danger to their lives.
4. A scene in reality will feel as if it has been experienced. I believe you should have experienced it.
I met a difficult problem in junior high school, and my dream was actually solved. I woke up the next day, so excited.
6. As you said, I dreamed in a dream. I woke up thinking I was really awake, but I was still dreaming.
There is no need to fight for a dream.
