Consciousness can function on many levels, for instance sleep.

"Sleep is a no-man's land between such consciousness on the physical plane and consciousness on the astral plane.

. From that state, to the extent the Attention can mobilize electromagnetic energies of the cerebral frequency and direct them to happenings on the physical plane, is the sleeper aware of what is going on about one in the physical world. Physical sensations thus reaching one's consciousness afford suggestions which give trend to one's dream "

The no-man's land of sleep.

"In the state of sleep, or similar condition induced for purpose, if the Attention moves neither out to become conscious of the material plane, nor in where velocities exceed those of light, the consciousness remains chiefly linked with electromagnetic energies, and because it is not fully conscious on either plane, but in the no-man's land where Boundary-Line energies are dominant, it is highly susceptible to suggestions and devoid of discrimination."

Foreseeing future events in one's dream.

"Almost anyone who systematically endeavours to do so, and turns the Attention of their soul to the inner plane during sleep, and over a few weeks keep a careful records of their dreams, will become convinced that their consciousness has become aware of some events long before they happen, or could be surmised from ordinary waking sources."

"Such dreams should be regarded, not as complete inner awareness of the details of the future event, but as a distortion of the fantasy thinking common to the no-man's land of sleep by the impacts of stimuli relating to the event from the astral plane".
