What do you think this dream means? It was very disturbing..?

It might just be a manifestation of your repressed feelings. Not necessarily ual feelings, but maybe you've kept your opinion from people to spare their feelings, or that you haven't been able to voice your opinion because you weren't given the chance. Usually, ual dreams aren't about the at all, but about the aggression and openness more than anything else. Hope that helps! :)
