138 SKETCHES OF GREAT TRUTHS Most of us sleep about seven or eight hours a day taking but little account of the hours spent thus ; they are as important as the hours of our waking consciousness. As a rule we do not bring back our experience on the astral plane, which is where we spend our time in sleep, yet there are many instances of work done there, the remembrance of which has been brought through to the waking consciousness. Sometimes there is a partial bringing back into consciousness, the result being a jumbled up dream with little or no meaning, but not unfre- quently, what we call dreams are real happenings on the astral plane. Our interpretations may often be incorrect, seeing that we are apt to colour happenings there by physical sight, hearing, etc,, this is from want of experience and knowledge, but there are possibilities of training ourselves, so that we can bring back more clearly the happenings when we are out of the body in sleep. When a man falls asleep, he withdraws in his astral body, leaving the whole of the physical vehicle behind him. When he dies, he draws out with him the etheric part of the physical body, and consequently has usually at least a moment of unconsciousness while he is himself freeing from it. Some men succeed in shaking themselves free of this etheric envelope in a few moments ; others rest within it for hours, days or even weeks.
