I would suggest that you tell yourselves that you will henceforth be able to remember dreams from the deeper levels of your personality, and you should find that you will be able to do so. You can also tell yourselves when you wish that you will give special attention to the nature of time and space, as these appear within your dreams. You will discover then upon awakening that many perceptions concerning time and space within the dream state will remain within you.

Stir up thy mind, and recall thy wits again from thy natural dreams, and visions, and when thou art perfectly awoken, and canst perceive that they were but dreams that troubled thee, as one newly awakened out of another kind of sleep look upon these worldly things with the same mind as thou didst upon those, that thou sawest in thy sleep.

It is just over two years since we came here, two years of a dream life rooted in one spot, with the same few individuals to see, the same limited environment, the same routine from day to day. Sometime in the future we shall wake up from this dream and go out into the wider world of life and activity, finding it a changed world. There will be an air of unfamiliarity about the persons and things we see; we shall remember them again and past memories will crowd into our minds, and yet they will not be the same, nor will we be the same, and we may find it difficult to fit in with them. Sometimes we may wonder whether this renewed experience of everyday living is not itself a sleep and a dream from which we may suddenly wake up. Which is the dream and which is the waking ? Are they both real, for we experience and feel them in all their intensity, or are they both unsubstantial and of the nature of fleeting dreams which pass, leaving vague memories behind?

In order to awaken, first of all one must realize that one is in a state of sleep. And in order to realize that one is indeed in a state of sleep, one must recognize and fully understand the nature of the forces which operate to keep one in the state of sleep, or hypnosis. It is absurd to think that this can be done by seeking information from the very source which induces the hypnosis.
....One thing alone is certain, that man's slavery grows and increases. Man is becoming a willing slave. He no longer needs chains. He begins to grow fond of his slavery, to be proud of it. And this is the most terrible thing that can happen to a man.

We are close to waking when we dream that we are dreaming.

Sometimes it’s important to wake up and stop dreaming. When a really great dream shows up, grab it

Eventually, it begins to seem as if you are repeatedly awakening from a dream to find yourself safely in bed. No matter how terrible the dream, the relief is instantaneous.

We know only the ordinary states of consciousness in which we live; we do not have complete knowledge of reality. When we are awake, we are totally immersed in our waking world. When we dream, our activities, our world, and our understanding are completely different from when we are awake. When we go into the state of deep sleep, we lose consciousness altogether.

Dreams are associated with a state called REM sleep, the abbreviation standing for rapid eye movement. The REM state is strongly correlated with sexual arousal. Experiments have been performed in which sleeping subjects are awakened whenever REM state emerges, while members of a control group are awakened just as often each night but not when they're dreaming. After some days, the control group is a little groggy, but the experimental group - the ones who are prevented from dreaming - is hallucinating in daytime. It's not that a few people with a particular abnormality can be made to hallucinate in this way; anyone is capable of hallucinations.

But when you can’t sleep at night, how can you dream?

When you awaken -- or seem to awaken -- in the middle of the night, try to get out of the body and go into another room. This is a pleasant and easy method. With some experience you will discover that you can maintain control, walk out of the apartment and outside. You may then attempt to normal locomotion or levitate.

A still greater control is exerted over the thoughts during seep by their character during hours of wakefulness. By controlling the mind during entire consciousness, it will also be controlled during unconsciousness or semi-consciousness. Dr. Acton makes the following very appropriate remarks of this subject:- “Patients will tell you that they ‘’cannot’’ control their dreams. This is not true. Those who have studied the connection between thoughts during waking hours and dreams during sleep know that they are loosely connected. The “character” is the same sleeping or waking. It is not surprising that, if a man has allowed his thoughts during the day to rest upon libidinous subjects, he should find his mind at night full of lascivious dreams--the one is a consequence of the other, and the nocturnal pollution is natural consequence, particularly when diurnal indulgence has produced an irritability of the generative organs. A will which in our waking hours we have not exercised in repressing sexual desires, will not, when we fall asleep, preserve us from carrying the sleeping echo of our waking thought father then we dared to do in the day-time.”

During our dreams we do not know we are dreaming. We may even dream of interpreting a dream. Only on waking do we know it was a dream. Only after the great awakening will we realize that this is the great dream.

Awake from dream, the truth is known: awake from waking. The truth is: The Unknown
