The practitioner tries to immediately separate from his body without using any techniques for creating lucid dreaming state: simply roll out, levitate, stand up, crawl out, etc.
Phantom wiggling technique
lucid dreamingr tries to move some part of his body without moving a muscle, and meanwhile without imagining or visualizing anything. For example, this could be an arm, leg, shoulder, the head, or even the jaw. When movement arises, the main aim is to increase the range-of-motion as much as possible, but not necessarily the speed of movement or the portion of the body part being wiggled.
Imagined movement technique
a lucid dreamr tries to realistically feel some movement that he starts off by simply imagining. For example, this could be swimming, running, walking, flying, or peddling with the legs or arms. The practitioner doesn’t have to visualize the technique when performing it, as movement itself is most important here.
