Browsing the forums I find that a lot of people talk about exploring their dream world, talking to DCs, and accomplishing various goals they have set for themselves. Why do we do it? Just because we can? In the few lucid dreams I've had that lasted longer than a few seconds, I follow a story. I will either continue the plot the dream has set for me, or I will create a new story and steer it in my desired direction. I feel an alternate reality inside my head needs an alternate story line. That, and it's just incredibly fun. I can accomplish the unthinkable, but if I do, don't I want it to feel as real as possible? I want to do crazy things and feel the impact of my decisions, I want to feel like my dream characters are real, and I want to be a hero!
I also think that this helps greatly with dream control. If I have a reason to be able to do something in the story, I should be able to do it, right? If I am a superhero, for a simple example, I should be able to fly or do other such things. Only once have I even tried to do something that I didn't assume I could do had the story been real, and that was in a really strange semi-lucid dream. I have also become lucid, successfully remembered a story from a really fun lucid I had before hand, closed my eyes, imagined myself where I was when I woke up last time, opened my eyes and continued the story where that last lucid had left off.
I guess the question I'm asking is: do you guys need a story? Why or why don't you follow a plot? And do you try to continue stories from previous dreams?
