Dream About Pool Party 2

This dream was actually such a good one that when I woke up I cried BECAUSE it wasn't real....It was a pool party at my childhood home, many people were there none of which I knew in real life, I arrived there with two people who I don't know IRL but In the dream they were my friends, a boy and a girl who one of the random people in the dream called "the Brady girl" because she looked like she could be from the Brady bunch, anyways we were all in the pool with music playing and everyone was having fun,some people were jumping in the water with their business suits on, or their everyday clothes, we were all going in a bit circle in the pool to try and make a whirlpool, there were 3 people there in full dog mascot costumes,my childhood pets were also there...eventually In the midst of the whirlpool thing I realized I couldn't find my friends I came with, and figured maybe they went inside but I was still having so much fun singing along to the songs and giggling with people, I stopped for a second and looked into the window from outside to the house to see my biological dad sitting with my stepdad,playing his drums,having a blast,I turned around and told a couple of people "he never misses an opportunity to play the drums" and got back in the pool, then one song came on and everyone knew the lyrics including me even though idk if it's even a real song irl lol, but the whirlpool continued at this point it wasn't taking much effort to kind of just float along because there were so many people in the pool, everyone was styled as though they were from the late 70s, like boogy nights/disco look, and I remember thinking everyone looked so nice and how interesting it was that the style had made such a comeback and was just thinking about how much fun I was having and there was a lot of random talking to people who were there just here and there small stuff but it felt nice ...it felt like everything was as it should be...then when I woke up to see it was a dream I was incredibly upset...I literally cried.
