Dream About Feeling Upset While Other People Leave

This dream was about

Last night I had a dream that somebody I knew named Heather and another person I knew named JR were helping me with a bunch of art projects in a school cafeteria with a bunch of kids and they decided to take off on me but I didn't know what was going on and I didn't know how to handle the kids. Well the kids thought I was upset and they asked me if I was upset. I said no, I'm not upset. As they were leaving, JR wrapped his arm around Heather and it clearly made me upset because the other person that was there helping me was asking me what was going on as I was wiping down the tables because there was water everywhere and I could see the children's paintings and I was fixing up their paintings and you could just tell that there was something going on between Heather and JR although Heather wasn't Heather, she was an older woman. From the cafeteria I entered into another room where there was a bunch of like sea life and one of them was a betta fish that kept jumping out of the water and I couldn't figure out why it was jumping out of the water so we decided to dump out its aquarium to figure out what was going on and there was a hog nose being eaten by a bunch of mealworms and when I looked up to retrieve it out, my kid's dad was standing there instead of my kid.
