participating in the PE and the map's/sketch's purpose is to help them reach the target PE area.
I got the sketch of the area by nonphysically sensing my surroundings at that place
over several sessions. It should not be viewed as blue print of the area, as that may
easily change because of its volatile nonphysical nature.
The beings (humans, aliens or guides) appearing at the place are in their nonphysical form.
