Dream meanings?

Im not sure where to post this. For the past two nights i have dreamed about my soon to be ex husband. The frst night i had a dream that he honestly was just really really mean to me. He would make nasty comments to me. Last night i had a dream that i was hanging out with my friends at school (i was back in high school) and all of a sudden he runs toward me, pushes me in a pool and tries to drown me. I was saved by several people and he was kicked out. Does anyone know why i am dreaming about him being mean to me all of a sudden??
