“Seth material” search engine (Jane Roberts)

Now, using an analogy only, let me explain that your thoughts and feelings also give off shadows (intently) that we will here call hallucinations.² They are quite valid. They have as strong a part to play in dream reality as shadows do in the physical world. They are beautiful in themselves. They add to the entire picture. A shadow of a tree cools the ground. It affects the environment. So hallucinations alter the environment, but in a different way and at another level of reality. In the dream world hallucinations are like conscious shadows. They are not passive, nor is their shape dependent upon their origin. They have their own abilities.

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.

In the dream world, however, each feeling or idea can be immediately expressed and experienced. The physical world has buildings in it that you manufacture — that is, they do not spring up naturally from the ground itself. In the same way, your thoughts are “manufactured products” in the dream world. They are a part of the environment and appear within its reality, though they change shape and form constantly, as physically manufactured objects do not.
