Well I wish you luck with your construction.
Sometimes I find that if I write out a dreamscape or draw it, it doesn't work anymore for me, it's that I've taken it out of my dreaming mind, and placed it into the waking world I think. But that's just me.
As far as dreams go, I had a very interesting one last week where I was an amnesiac. My memories only went back as far as 13, when I was adopted.
I lived on my own now, and spent most of my time in the ocean. I liked swimming in the evening when no one was around.
It was on one of these sunsets that I saw something drifting towards the shore. I swam to it, and found that it was a coffin tied to a piano and a trunk.
I swam to shore with it, where two reporters were waiting for it to hit land. Someone told me that it was the coffin of my lost grandfather. Which was wonderful news, because I might get some of my memories back. (even more facinating, because it was the night before my grandpa died) But I wasn't thinking about these things in the dream. I was only thinking about how much I wanted to make this a more interesting dream. So I changed it.
When you change a dream while you're dreaming, you have to be extremely vague, and rather blunt. You don't have to worry about rewriting the whole thing. All you need to do is intergect one small little plot twist, and the dream will restructure itself around you.
The piano was broken, and sunk down from the coffin. I dived after it, and picked at it's wooden keys. It was old, and felt familiar.
I came to shore. The reporters told me to leave, because this was now a police investigation, and I had no right to be there. They start going through the things in the trunk, and I feel offended and violated.
(here's where I change the dream.)
"But I'm not dead!" I yell.
The reporter man looks at me like I've gone crazy, "Of course not."
The dream was shifting slowly, and it was hard to get the new set of rules out of my mouth. I pointed to the coffin, "I'm not dead." there, engraved on the coffin, was my name. At first I was surprised to see it, but then I realized how the change was working. It's like being an actor, and suddenly, half way through the play you start to improv. It's takes a while for everyone to catch on, even you.
They still look at me like I've lost it.
Then I bring the name to their attention, "That's my name." and I knew that to be a fact, "But I'm not dead." And now the dream was mine, completely patched up, and it's only going to get more interesting from here. I can see the change go through them, and the original dream faded completly.
I could feel strange memories coming back.
I told them to stop going through my things. And then another strange thing just flew from my lips, "You could have disturbed the elixir of life."
"The elixir of what?"
Huh... I hadn't expected that. it had started out as a joke on my part. But then I had the strangest feeling that I was much, much older than 20. And another fact came to me.
"It's like the drink for imortality, but not really... it just lets you live as long as everyone else, but retain your youth. Or longer..." I had a feeling I was in my 80's... which is a strange feeling to have when you don't remember anything.
At that point, the woman reporter wanted to test me on some of the things that were in the trunk, that I hadn't seen yet. She wanted me to draw some emblem. Which I just guessed at, and managed to get right.
But the coffin was a warning, and someone was trying to kill me, which meant that someone knew more about me than I did. And I needed to get my memories back soon.
dream fades, I feel the hints of To Be Continued.
Before I wake. I get a glimpes of what the dream could have been before I changed it. I was reliving some of my grandpa's memories from World War II. They were pleasent memories, and I enjoyed feeling closer to him in this way.
