“Seth material” search engine (Jane Roberts)

The author whose book on precognition you are reading comes quite close in important respects.

All systems of reality are created, or constructed, by those who perceive the system. Those who do not construct a system cannot perceive it. Now. There is nothing at all unusual in precognitive experiences. They occur constantly beneath the level of your awareness. However there are certain conditions necessary before precognitions can arise to conscious levels, and there are definite conditions that must exist before what you call apparitions can be perceived.

This particular kind of dream is concerned with working out certain problems concerning your physical reality, and they are usually not precognitive. They might appear precognitive if you perceived them, because many of the events contained therein will later occur in fact. They are not precognitive however, for in a large measure they bring about, or cause, physical events.
