Has 3 parts in my last dream

Date: 3/20/2020

Last night I had a dream where I can vividly remember three parts. I do not know the order these three events happened, but those were the events where I can somewhat remember vividly during my dream. One part reminded me of Sunday school. I was at home. I do not know whether it was raining or thundering, but I remember it was definitely during the evening. I’m at the exact house I’m currently living in with the exception of one thing: a long wooden table where one end stretches from the kitchen to the kitchen room at the other end. I remember my parents inviting some “students” quote on quote to have tutoring sessions. This reminded me of Sunday school, where I had to sit at long tables that were made of wood and can be folded. The next part was really short. It’s like an outdoor science class well not quite. This time it did not happen inside my house, but in a gym-like setting with whitish walls that I don’t remember in detail. Then someone had a large pump that pumped lots of methane gas for demonstration purposes. I remember sniffing the methane gas as more and more was pumped into this room. The smell gave me flashbacks of my lab classes I had in college. The last part that I could remember was in a mysterious area That had floating platforms I can walk to. One of the platforms was shaped like an L which was very similar to a motel. Only that the colours were mostly pinkish. I was walking at the “motel” like hallway in the L-shaped building and then, I started walking on a platform I can’t see, as if I was walking on air.
