“Seth material” search engine (Jane Roberts)

Physically, an oak tree may cast a rich deep shadow upon the ground. It will move, faithfully mirroring the tiniest motion of the smallest leaf, but its freedom to move will be dictated by the motion of the oak. Not one oak leaf shadow will move unless its counterpart does.

Since these are far more lively than ordinary shadows, and are definitely more colorful, they may be more difficult to distinguish at first. You must remember that you are wandering through a mental or psychic landscape. You can stand before the shadow of a friend in the afternoon, in waking reality, and snap your fingers all you want to, but your friend’s shadow will not move one whit. It will certainly not disappear because you tell it to. In the dream world, however, any hallucination will vanish immediately as soon as you recognize it as such, and tell it to go away. It was cast originally by your own thought or feeling, and when you withdraw that source, then its “shadow” is automatically gone.
