For example, your dream task is an attempt to narrow down the choices or to make a decision, and one should see the intuitive options, which means the ratio should be inactive. In this case, there’s no need to wake up in a dream, for as soon as one gains awareness, rational thinking will be turned on, and the current dream world will be maintained by one’s own recourses and thoughts.
To receive information in a lucid dream is the same as to ask yourself the same question in your usual life. There is no difference. You see? No difference at all. Reality and lucid dream are the same for informers. Lucid dreams can ‘happen’ in astral – this is the first metaphysical plane after the physical one. And you can wander along astral as long as you have energy for that, but you won’t perceive more than resemblance of physical world filled with light covers of mental activities of living creatures.
