Dreams are another vehicle of consciousness. Your experience with in the astral dreamscape is what makes it 100 percent real. If your being chase down by a lion in a subconscious dream would you not have the same level of fear as if it were happening in waking physical life. Think of dreams as reality 2.0 where rules like gravity are optional and where there are no limits to what u can do or learn. Gd luck in your pursuit of lucid dreaming. It can be a very rewarding experience. Namaste.:-D
