Dream of father, married, mother

My mother in law married my dead father in law's ghost. She could see his ghost and decided to have a wedding ceremony. As part of the wedding preparation, I cut my hair in a short bob and coloured it blond. My partner and I were dressed and waiting on the couch for everyone else to get ready and I was 6 months pregnant (I'm currently 4 months pregnant). We started kissing, which triggered my partner's gag reflex and he threw up on me. I then got in the shower with my clothes on and when I got out, we went to the wedding, drenched clothes and all. At the wedding, everyone thought my father in law's ghost didn't pitch because no one could see him but my mother in law said we must continue with the wedding as usual, so we did. She was alone all through the wedding, saying her vows alone at the altar, and she was alone at the reception. Later that night, me and my partner browsed through the wedding photos we had taken, and my father in law was right next to my mother in law in every picture.
