This technique is performed by walking or flying through a wall with the eyes shut and a firm conviction that the required location is behind the wall. The barrier does not necessarily have to be a wall. It can be any non-transparent object through which a practitioner may walk or fly: a screen, a wardrobe, and so on.
The main drawback of this technique is the necessity of appropriate skills for penetrating through solid objects of lucid dreaming. Another necessary condition for applying this technique is the presence of barriers to pass through.
