Friend drumming + washing toilets!

I probably dreamt even more than this, but I can clearly remember a dream where one of my friends were playing drums on a concert. It was old Opeth songs (and he has nothing to do with Opeth haha, but... I do) and he wasn't usually playing drums. It was all taking place in the church too. I was the one helping or instructing him, sort of. I stood or sat somewhere infront of the drum kit and pointed at cymbals and was amazed by his good job!

Great! Now I remember the other dreams too.

Me and... many, many other people were in a house or a factory or something. We were under the power of some evil or bad guy, and he threatened to... something bad if... we didn't clean his toilets. He had like hundreds of toilets, and every once in a while, while we were working with something else probably, he rang a bell or gave a signal that we had to wash his toilets. Everyone ran around in panic trying to find a toilet to wash, because if you didn't, you'd get punished. Later in the dream, me and another guy who seemed very hardcore got a task. We were gonna make some kind of cake or something. Seriously, here's what we had to do. We went downstairs with lots of ingredients. The ingredients seemed to consist of big lumps or chunks, or whatever it was, of something weird. We went into the bathroom, and the hardcore guy who was screaming all the time because he felt he had an important job to do, ripped off small bits of the weird lumps and threw them into the toilet. It seemed to make sense in some distant way... I don't remember what happened after he had put all the ingredients from the weird stuff I can't remember what really was, into the toilet, which would eventually make a cake.
Later in that dream, I was walking around in the streets, probably with some friends, but that feeling of being under the pressure of that dark master with his toilets was still there. I actually think I woke up a few times after the first dream, had that feeling, and went back to sleep and continued the dream in another way. The rest is very unclear, but I think part of it took place in some factory or business where I took control myself. Too unclear. Was fun though!
