Weird dream about chemistry class

The experiment involved Saxophone reeds and Joe was playing some sax and i asked him what kind of sax he plays and he goes ‘oh, i play round saxophone’. I was like tf bro.
I wanted to play (to impress a girl) but i was really thirsty so i went to get water
Teacher lives in a mansion now apparently. I try to look in his fridge for water but it is very complicated and there are tons of containers with rotten milk, no water at all. I go to the sink with a weird cup i found and fill it up with water. I try to drink it but the bottle converts water into bubbles. I was extremely fatigued so I could barely carry the plastic water bottle and turn on the sink. His house was slanted for some reason
Then i went into his Living room. I asked him why his house was slanted and he gave a nonsensical explanation. Then the fridge slid across the house. Also two random buff mexican guys are talking to my teacher about house repairs. The living room had an upright piano with wide keys and only like 30 of them, and a normal upright piano (not an important detail but i felt it was interesting)Then i see Jon (not Joe) and he says he has to leave early because his dad is about to purchase San Fransisco. teacher is visibly upset by this
I go to the exit of the house and a concierge at the door says i cant leave because class isnt over, then gives me a wine glass to get water. I go up a spiral staircase and find out that teacher's mansion is also a college campus, and there a shitload of kids. Also at this point i just did not have my shoes on for some reason. (Which i clearly remember being confused about it in the dream, not ever taking my shoes off at any point)
Then i go down the stairs again, and when im looking for a sink I see  my little brother hanging out with his friend wes. They took off their shoes and were trying to dance. the section of the mansion closely resembles our house at the dinner table. I can see our family twice. They are in the computer room and also in moms bedroom. After they stopped dancing, Wes goes with my little brother, mom and Dad. They start playing garage band in the master bedroom. Upstairs, Mom, Dad, my little brother and older brother are jamming out to Stayin Alive. I think its weird but pass it off as normal. Then i finally find water source but the water is not quenching at all and its extremely difficult to swallow. Then i wake up by trying to swallow.
