Dreaming in Digital

I remember something about being in the world of Harry Potter. I was a student at Hogwarts. There was the old dude, and someone else, but I don't remember who. You can tell I'm not a regular fan of the books.

I went to meet my Uncle Joven and Aunty Boots at an aquarium show with my mom, dad and sister. We sat down and the show ended. The stage in the centre had a podium with five bells. While my uncle nad dad messed with something on stage, I played with the bells, specifically three of them, playing a tune. My aunty was impressed and asked which how did I play it and I showed her with my mom watching.
