I've been having a number of semi-lucid dreams. These are dreams in which I am aware I am dreaming but still play along with the plot of the dream. I have been wondering why I do this, as opposed to performing experiments on my dream scape.
Dreams can be fun: the have intense plots where you can do outrageous things that you can't do in real life. This I am beginning to believe, is the reason I remain semi-lucid. When thinking about my dream experiences I am beginning to notice the more lucid I am, the less activity there is in the dream. As my lucidity increases the stimulus in my dream environment decreases. I stay only semi-lucid because I want to 'ride the wave' of my dream.
This leads me to think that perhaps as the lucid conscious process ramps up it starves resources from the dream construct, almost like there is a trade-off between the two - only so many brain resources. As in a sense reality is a constructed story, perhaps when we don't have a majority of reality construction outsourced to the real world there has to be a trade-off of what can be achieved with the brains finite resources.
Its almost like the high level constructs the reality and the reptilian experiences it.
