I just received your dream and I had the pleasure to interpret it for you. What you need to know is that this type of dream is not necessarily a premonitory sign of the return of your ex. I will give you all the meanings of the symbolism of your dream in the following lines.
Cristina, the main part of your dream revolves around your ex-in-law, and you should know that this is not insignificant, because your ex-in-law symbolizes unresolved emotional and personal problems.
The presence of your in-laws is a sign of a decision that you need to make in order to keep control of something important.
Be careful, because it will not be easy, your subconscious wants to alert you to the fact that you will have to surpass yourself. This is the reason why you are arguing with your brother-in-law in this dream, it is a bad omen.
In fact, Cristina, this argument is a sign that you are probably going to have an argument soon with either your current spouse or a close friend or relative. Your subconscious mind is telling you to carefully identify the slightest signs of an argument and to avoid it as much as possible, because it could get worse.
However, there is some good news in your dream, and that is the fact that you are walking towards that other house, which symbolizes the evolution and progression of your personal life. Your subconscious is inviting you to trust yourself, as you need to assert yourself in your environment.
In the end Cristina, you are on the right track, for the stitches you saw symbolize the steady progress you will make over time.
