Why will my dream come true in reality? What's going on here? Will everyone do this?

Yeah, yeah, me too. I have found this since I was a child. Every time I feel that the scene is deja vu, I have dreamed about it in my dreams before, but it is unpredictable and inevitable. I clearly remember that I dreamed that two teachers quarreled in the first grade, and as a result, they really quarreled in the third grade (note that I didn't know these two teachers in the first grade), which is a familiar scene when I watched them quarrel. Same place, same scene. It just flashed through my mind and I was completely confused.
