Dreams are usually black and white, black and white movies, not color. Few people dream in color.
Some people say that they had a color dream, which was added after waking up.
Of course, some people do have color dreams, but very few.
Let me talk about the unscientific side.
There are two diametrically opposite explanations of color dreams: auspicious and unlucky.

Your dream seems a little erotic. And the unique place is: monochrome dream! If I remember correctly, then this red dream with only a single color is really rare.
In fact, in my opinion, your so-called monochrome red dream is still black-and-white film (black and white dream)! Because there are only red and non-red in your dream, it just proves that your dream is black and white. Maybe you don't understand, but you just have to think that there are red things in black and white movies. Think of black and white photos. Your dream is black and white, but in the shooting scene (dream), you know what is red.
Go back to dreaming.
According to your memory, there are three things in the red tone: clothes/houses/boxes.
Oh, my god These are the "concretization" of your thoughts on marriage and/or housing problems in your dreams. You are thinking about these two aspects!
