Journeying is much like dreaming, yet unlike dreaming you retain control of yourself and the situation. Even when it seems like the journey is going in a direction you didn't choose you always have the power to stop it. To begin the first thing you need is a quiet place where you can sit or lie where you will not be interrupted during your journey. Then you need to prepare the space. Music can guide your journey.
Silence is sometimes best.
Play around some until you find what works best for you. If buying CD's try to listen to them first. I bought this CD that was supposed to be tranquil and calming. It turned out to be a recording of moos and clanking cowbells. I laughed too much to have a successful dreamtime.
