From your description, you care about details.
First of all, your dream has been telling one thing, that is, the road you walked, or the road you walked.
From a psychological point of view, perhaps this is a subconscious memory.
If the person in your dream never appears in your life, it can be understood as a disguised hint in your memory.
Recall something in the past, something you have forgotten.
For going down the stairs, at this time, if it appears at the end of the dream, it may mean that you will need to put down what you can't put down.
If it appears in the middle, it may represent a turning point in something. Simply put, you may have done this before, when you were a child, or a few years ago, or a few days ago.
If you really care too much about this dream, then I suggest you try to find the place in your dream, and you may have more feelings after seeing it.
Mind you, dreams are wonderful things. They often reflect people's hearts, and the results are unpredictable. If you can, don't care too much.
