1, your question involves a basic knowledge about dreams: dreams are mostly black and white films, and few people dream in color. Some people recall colors in their dreams, but they actually add them after waking up. You can say that the red flag is red in black-and-white movies, but it is gray-black in dreams.
2. Some people often dream about the same content. I call this kind of dream with little difference in basic content "theme dream". I think it is an important topic to study theme dreams, because it is a reflection of deep psychological accumulation, and dreamers need to cooperate with researchers to find out the reasons. Especially the real situation of the dreamer, including life experience, objective environment, personal quality, personality and so on. It seems that you are a dreamer with a theme, but we can't make a bold and accurate judgment based on your description of the dream, and we can only guess at most.
Some people have repeated similar dreams for many years, which I call "continuous dreams". The duration of continuous dreaming can be long or short. I have been dreaming for about 25 years, which seems to be inconsistent with reality, but I know that it is a comprehensive and tortuous performance of real life and early subconscious mental state. You have been dreaming the above dream for many years, and it is also a continuous dream.
Combine 2 and 3, and you have a continuous dream and a theme dream.
Therefore, I think your question is not "why do you always dream at night", but "why do you always dream about such a theme continuously".
5. The basic content of your dream actually reflects the following theme: the night view of the town where you lived as a child.
6, you have to prevent a misunderstanding: you can only dream at night. (The reason is omitted)
As for what your dream of "night market scenery" shows, it is difficult to get a satisfactory answer here. If you barely answer, A is probably related to an experience in your childhood and its brand in your heart, but B may also be a tortuous reflection of your present situation and living conditions (this is very complicated and difficult for you to understand). If it is a, it doesn't matter much. If it is B, and it causes psychological burden, it should be solved. In my experience, once it is really solved, this theme dream will disappear, at least not often.
8. We actually study your psychology and personality through your dreams. You don't have to worry about it. Finally, I want to say that this dream has no writing on the wall, and it is very warm and reassuring, so there is no need to worry at all.
Have a good time.
