Creepy dreams I have Pt. 1: Piano man

I had this dream a few years ago, it started with my sister, cousins, and I playing basketball outside our house. I then told them that I needed to buy envelopes, so we walked into the house which became a dollar store, I went and stood right in front of the envelopes and told my sister that they didn't have any. So we left and went to my aunts house.

She was having a masquerade ball, all of my family was there, and they were dressed in big ball gowns in a big ballroom. Now my family isn't by any means rich, so the fact that my aunt had a giant ballroom in her two-bedroom house didn't make sense to me, even in the dream. 

but I just shrugged it off and thought she must've rented it out... and somehow attached it to her house. Anyway, I saw there was a piano, so I walked over and sat on the bench, I tried to think of what song to play and decided that 'Fur Elise by Beethoven' (the only song I can play on piano) was it. So I began to play and when I was done, I looked up and saw that a man in a tailcoat suit with a plague doctor's mask and a wide-brimmed hat was watching me play.

He said "you played the piano, that was my job. Now you must sleep by the fire" 

I said "ok" and got up and went into the living room, my uncle, two of my aunts, and my cousin were sitting on the couch watching 'Bubble Guppies' (it's a kid's t.v show if you don't know) I told them "you guys got to move, I need to sleep next to the fireplace because I played the guys piano." 

my cousin looked at me and said "no, you need to sleep in the fire and burn for your sins."

so I looked at her and said "um, ok?" 

I then went outside and saw that there was this huge backyard that had a literal forest in it (which my aunt didn't have a big backyard) I walked all the way across and to the edge of the woods and there was a creek running along. 

Then there was a bright light behind me and I saw that my aunt's house was now a mansion and on fire. I then looked to the right of me and saw the man again, he stuck out his hand and said "come on, let's go" I took his hand and we began to walk to the mansion.

Then I woke up. This honestly isn't the weirdest dream I've had, so I'll probably post the other ones. I'm sure there's some kind of religious aspect to this, but honestly, I don't care enough to try and figure out what.
