Hello, I can tell you the symbolic meanings of your dreams symbols and that will help pull your dream meaning together.
Marriages in dreams can represent some kind of real life commitment of some sort. In your dream it was with someone you didn't want to be with, so that could speak to a dislike for whatever the real life commitment is, something you are against. something you are uncomfortable with.
Having only one day to organize things could speak to you feeling rushed or pressured into this commitment, maybe even overwhelmed and unprepared.
See if these connect with what is happening in your life.
If you have any questions please ask, I am happy to help. Thank you.
