Dream field environment one; I dreamed that I was on the stairs.
Dream field environment II; I started to control myself down the stairs ... and then suddenly I woke up.
So at least from this point, it should be Shuang Meng.
In dreams, all memories come from consciousness. Maybe you will realize that you are dreaming, but when did it start and what should you do afterwards? So the landlord is in a dream, only knowing that I am "aware of my existence", but I can't control the change of the dream scene. It is memory that controls the dream scene. One second it is in the stairs, and the next may be in the dormitory. Whether you know you are dreaming or not, the dream scene is already planned, because you haven't the ability to control the dream, so you can see that the landlord is like watching a live movie for free.
Generally speaking, the landlord should have had a vague dream from the stairs to the dormitory.
