You're in a dream. You don't necessarily know it, but you do know that that half-dragon-half-rabbit is about to take you back to its nest to feed you to its baby elephants. So what do you do? I have no idea, but assuming the dream continues, you will make a decision, and you will believe that all of it is real; the half-dragon-half-rabbit and your decision about what to do. So what's the difference between a real-life decision and a dream decision? I would say impact, but dreams can often haunt us much more than those little, seemingly inconsequential decisions we make alone. This question comes about as speculation about the possible need for Confession (as a Catholic) after dreaming about choosing to PMO. There have been many dreams where I can recall actively deciding to PMO, so why were those decisions any less real in their manifestation of will than ones I would make in the real world? Since this website is partly of a scientific nature, I would also like to propel the discussion of dreams in relation to psychology and philosophy, especially with respect to their perceived utility. [Edit:] As a thought experiment, take, for example, Inception. The only affect that any of the actions taken in the dream sequences of the movie have are of a psychological nature. The main difference with Inception is the presence of other dreamers in a dream. It is not lucidity, as lucid dreaming is certainly possible. However, having others present in a dream along with you could have the same outcome as simply telling those other people about that dream. Their rate of decay about the memory of the dream would be roughly the same as yours, and they would even form their own opinion of the dream scenario, even as told from your perspective. So what is the difference between a dream decision and a real-life decision?
