Okay you guys...I thought that this excerpt from the Agartha book is very apt for our little Dream Forum!
A different kind of meditation involves meditating into sleep. This type of meditation is different from the lengthy meditation and even the momentary meditation, for the last two seek to help you touch your soul energy while meditating into sleep, by contrast, puts you in touch with your own bodily energies so that healing and true relaxation can occur.
In meditation into sleep, you are striving to see and feel a sense of tranquility and to realize, as you seek to fall asleep, that your body and mind are working together in a productive way according to your soul's intended purpose. As you are falling asleep, picture your favourite scene: the ocean, the mountains, whatever immediately presents itself as a place of rejuvenation and peace. Experience the scene, either by remembering how it felt the last time you were in such a place (running your fingers through the sand, or crunching through the snow as you walk) or by imagining how it would feel if you were there. See yourself as calm, tranquil, and fulfilled. All worry has fallen from you, and you are totally unencumbered. Feel the confidence of being peaceful and knowing that you are living on purpose, even if disquieting aspects to your life remain. This positive image is important to present to the conscious mind, even if you do not really feel in control of your life, because your mind is responsible for restoring the physical body's balance and health.
Although your body is filled continually with energy, this energy becomes blocked, diminished, and detoured in your body by the experiences of the day. When you go to sleep in a state of consternation and confusion, the energy is not allowed to move to those areas that require regeneration, and you awaken in the same state of mind that you went to sleep in. And so take advantage of the period of entering sleep and ease your way into the night's expereinces and discoveries by meditating into sleep.
