Dream: The Language of Sin

I had a very interesting dream last night. It had a full, complicated plot, characters, everything.
Then I dreamed that I woke up and realized that I had an interesting dream, and wrote the whole thing down painstakingly. I dreamed I went back to sleep, satisfied that I would have this record of the interesting story.

Then I really did wake up, and realize that the whole thing was a dream, and I didn't have anything written at all.
Very frustrating! I often feel like I'm in the movie Inception. :p

What I do remember about the first interesting dream isn't much. It was a bit like a mixture between Gulliver's travels and planet of the apes. I traveled to another land, that was inhabited by people who were about 10 feet tall on average, and had green skin. They all dressed like the Victorian era, in dark formal suits and dresses. People like me were known to them, but were something along the lines of slaves/pets. They also had fire magic, which they could shoot out of their hands. When I visited, I was caught and enslaved.
The only specific instance that I remember is while I was sweeping the floor one day in my new master's foyer, I was called into the sitting room where he had guests. He told me to entertain them with a song. The first song that popped into my head was ave maria, which I started to sing for them. By the end of the first sentence, "Ave Maria, gratia plena, Dominus tecum," the guests gasped in shock. One woman looked like she was about to faint. My master's face contorted in fury. He gestured aggressively at me, and a ring of fire appeared around me.
"Go wait for me in the other room!" he spat.
The ring of fire moved towards the door, forcing me to move with it. It stopped in the dining room, not scorching the floor at all.
I waited for nearly three hours. It was very uncomfortable; the fire was hot, and too close for me to sit down.
When my master finally came in, he demanded that I explain myself. I stammered that it was just a religious song in Latin. I meant no harm, and had no idea it would offend.
From what he shouted at me, I learned that Latin (which they had another name for), existed for them, but each word meant something other than what I knew it to mean. The words that I had sung in the sitting room were apparently pornographic and threatening violence.
Latin was, apparently, the language of sin for this race of people. Only sexual libertines, thieves, rogues, and actors used Latin. To hear it in polite company was shocking.

I wish I really had written the rest down. I had a vague inclination when I woke up that it was a lot more interesting than these details that I remembered.
