Your dream sounds like a beautiful reflection of your recent experiences and your relationship with your dad. Dreams often serve as a way for our subconscious to process emotions and experiences, and it seems this dream highlighted your desire for quality time and connection with him, especially since you mentioned having three sisters and enjoying that one-on-one time.

The setting of a playground or carnival can symbolize joy, childhood innocence, and carefree moments. The laughter and running around with your dad likely represent the happiness and comfort you feel in his presence. The part where the camp director says you have to leave early and your emotional reaction to it might indicate a fear of losing those precious moments or a sense of impermanence in your relationship. It’s natural to want to hold onto those joyful experiences, especially after having a special day together.

As for your concern about the dream being a premonition about your dad's health, dreams rarely predict the future. Instead, they often reflect our current feelings and anxieties. This wholesome dream seems more about your bond and the joy of spending time together rather than any ominous signs.

Overall, it’s great that you found this dream memorable and meaningful, especially after a period of not recalling your dreams. It might be helpful to cherish these moments with your dad in real life and continue nurturing that special relationship.
