Reoccurring dreams/nightmares

I keep having these weird pregnancy dreams where my old high school bully is nice to me and loves me while the people I used to necessarily picked on gets revenge on me. (My ex’s ex makes fun of me in my dream, someone I used to hate.. weird relationship with them) What do these mean? It’s backwards and weird. Just confused as to what it means lol. I know we get weird pregnancy dreams but dreams always mean something
