When human beings explore astral dreaming, they do not necessarily sense what this is. As an astral dreamer, you will sense a different sort of reality and remember details that surprise you. How often do you ask yourself why you would like to astral travel?
Any human being can learn astral projection. Some people learn to project the body. Others project consciousness. Still either people learn to project either or both at will. In all cases, your awareness is heightened and you sense differently. You may create new points of reference. You may also sense your mind is playing tricks on you.
It is not uncommon for people to get a fright when they discover their fingers seem to be made of elastic and they can stretch them like taffy. Some people even wonder if perhaps they are dead because their insight and perspective change and grow so much.
Like anything, if you set your mind to the task, you can train yourself, develop mental discipline and venture to places you had not even imagined during waking consciousness. If you choose, you can engage in dialogue with people you haven't seen in a long time. As you erase or move beyond expectations that emerge from what you have heard from other people about astral travel, you will move to create your own personal experience.
