This is an interpretation that I have often seen in people. You dream about people you knew in the past and suddenly they appear in your dream. Nothing has happened in your current life that warrants them appearing again. So what meaning can we give.
And I always had two possible interpretations, either that where they are, they remember you, or if the loss of contact is an argument or something serious, then the dream tells you that it is up to you to do the first step.
They just remember you
This is the first interpretation, it can be the dream of your childhood friend, of your former loves, you have lost them for several years and they appear. Nostalgia is a powerful feeling in dreams, it can connect you even when you don't want it to.
It is that in their current life, they remember of you and it appears in your dreams. It can also be because they are going through a difficult time and we can see this how they appear in the dream. Are they angry, do they seem stressed, etc.? If you just lost contact without animosity, the dream is telling you that you should worry about it because you were together at one point.
Repairing past mistakes
And in the 13 years that I have been making these interpretations, it is this second interpretation that often applies. You have lost contact or decided to separate from someone. This could be your ex husband, ex wife, family members, etc. We are talking about serious arguments here and if they appear in your dream repeatedly (this last point is very important), then it means that it is an outstanding thing in your life and you need to fix it.
Allah is said to be a very fair and terrible accountant. Every action is counted and if you have done something wrong to that person, then you must ask for forgiveness (know that the greatest forgiveness begins with oneself, because there is no greater judge than one's own conscience ).
This reconciliation may be the key that will finally prevent you from progressing in your life. Our bad actions here on earth will cause us problems in this world. But I repeat, it is the recurrence of the dream that matters with the same people you have lost sight of. It's like a divine alarm that sounds at regular intervals to tell you what you need to do.
