This is a type of WILD I need u to help me on.......

THE TWIN BODIES TECHNIQUE

1. Relax completely - After awakening from a dream lie on back or right side with eyes closed. Tighten and relax whole body, breathe deeply etc. Let go of other thoughts and affirm intention to enter dream state consciously.
2. Focus on your body - Focus attention on each part of body and notice how it feels, watching for vibrations or other strange sensations. When these sensations arrive, following will be a complete paralysis of the body. You are then ready to leave the paralyzed physical body and enter the dream body.
3. Leave your body and enter the dream - As soon as the physical body is in a profound state of sleep paralysis, you are ready to go. This paralyzed physical body has a moveable twin, called your dream body. Imagine yourself in your dream body, rolling or floating out of your physical body. Jump, crawl or fall out of bed. Sink into the floor. Fly through the ceiling. This is lucid dreaming


I can get into SP easily but what does LaBerge mean when he says "imagine you are in your dream body"? Describe it to me in more detail please.
Thanks!
