It would start out with me gaining lucidity. Then I would take myself to a village area with a moat and a castle in it. I'd enter the village and explore there, every store would have what i wanted and all the villagers would give me what i want. They'd all be girls and all beautiful. I would stroll through the village, and of course... I realize i am the KING of the castle. I continue up to the castle through the village tasting the most delicious things ever in the shops.
Now i got to the castle. The doors slowly open while trumpets sound and guards bow to me. I walk through my castle to tthe throne and look at all the doors to rooms. I get to the throne and assume my position as king. In future dreams I would enter each door.... each door would be a different world. One would be just a blank world, where I could make items sort of like Gary's mod for half life 2. Another would be things like Atlantis or another world.

Fill in the other doors! let's have some ideas
