‎Our life is twofold; Sleep hath its own world, a boundary between the things misnamed Death and existence. Sleep hath its own world, and a wide realm of wild reality; and dreams in their development have breath, and tears, and tortures, and the touch of joy. They leave a weight upon our waking thoughts, they take a weight off our waking toils. They do divide our being; they become a portion of ourselves as of our time, and look like heralds of eternity. They pass like spirits of the past — they speak like sibyls of the future; they have power — the tyranny of pleasure and of pain. They make us what we were not — what they will, and shake us with the vision that’s gone by, the dread of vanished shadows — Are they so? Is not the past all shadow? — What are they? Creations of the mind? — The mind can make substances, and people planets of their own, with beings brighter than have been, and give a breath to forms which can outlive all flesh. I would recall a vision which I dreamed, perchance in sleep — for in itself a thought, a slumbering thought, is capable of years, and curdles a long life into one hour.

I have always been amazed at the way an ordinary observer lends so much more credence and attaches so much more importance to waking events than to those occurring in dreams. It is because man, when he ceases to sleep, is above all the plaything of his memory, and in its normal state memory takes pleasure in weakly retracing for him the circumstances of the dream, in stripping it of any real importance, and in dismissing the only determinant from the point where he thinks he has left it a few hours before: this firm hope, this concern. He is under the impression of continuing something that is worthwhile. Thus the dream finds itself reduced to a mere parenthesis, as is the night. And, like the night, dreams generally contribute little to furthering our understanding. This curious state of affairs seems to me to call for certain reflections.

But since the downfall of the mythological hypothesis an interpretation of the dream has been wanting. The conditions of its origin; its relationship to our psychical life when we are awake; its independence of disturbances which, during the state of sleep, seem to compel notice; its many peculiarities repugnant to our waking thought; the incongruence between its images and the feelings they engender; then the dream's evanescence, the way in which, on awakening, our thoughts thrust it aside as something bizarre, and our reminiscences mutilating or rejecting it — all these and many other problems have for many hundred years demanded answers which up till now could never have been satisfactory. Before all there is the question as to the meaning of the dream, a question which is in itself double-sided. There is, firstly, the psychical significance of the dream, its position with regard to the psychical processes, as to a possible biological function; secondly, has the dream a meaning — can sense be made of each single dream as of other mental syntheses?

Dreams give information about the secrets of the inner life and reveal to the dreamer hidden factors of his personality. As long as these are undiscovered, they

But then I have long since grown accustomed to the thought that what we call dreams is semi-reality, the promise of reality, a foreglimpse and a whiff of it; that is they contain, in a very vague, diluted state, more genuine reality than our vaunted waking life which, in its turn, is semi-sleep, an evil drowsiness into which penetrate in grotesque disguise the sounds and sights of the real world, flowing beyond the periphery of the mind — as when you hear during sleep a dreadful insidious tale because a branch is scraping on the pane, or see yourself sinking into snow because your blanket is sliding off.

A dream is by definition a series of sensations that occur in the brain when both our senses of perception and our powers of will and reason are in abeyance, so that we have no control over that flux of sensations. But it is, of course, a well-known phenomenon that when we dream that we are dreaming, the dream ends and we awaken. Then the conscious mind takes over and we are again responsible for our thoughts, and must face a day in which we must be responsible for our actions, which, by their wisdom or folly, may determine the rest of our lives. Our dreams may give expression, pleasant or painful, to our subconscious desires or fears. But in our waking hours we must, if we are rational, make our decisions on the basis of the most objective and cold-blooded estimates that we can make: estimates of the forces and tendencies in the world about us; estimates of the realities with which we must deal; remembering always that nothing is likely to happen just because we think it's good, or unlikely to happen just because we think it's evil.

About dreams. It is usually taken for granted that you dream of something that has made a particularly strong impression on you during the day, but it seems to me it´s just the contrary. Often it´s something you paid no attention to at the time — a vague thought that you didn´t bother to think out to the end, words spoken without feeling and which passed unnoticed — these are the things that return at night, clothed in flesh and blood, and they become the subjects of dreams, as if to make up for having been ignored during waking hours.

The dream is a little hidden door in the innermost and most secret recesses of the soul, opening into that cosmic night which was psyche long before there was any ego-consciousness, and which will remain psyche no matter how far our ego-consciousness extends.

May we not imagine that possibly this earthly life of ours is to the other life what sleeping is to waking? May not all our life be a dream and death an awakening? But an awakening to what? And supposing that everything is but the dream of God and that God one day will awaken? Will He remember His dream?

Of our studies it is impossible to speak, since they held so slight a connection with anything of the world as living men conceive it. They were of that vaster and more appalling universe of dim entity and consciousness which lies deeper than matter, time, and space, and whose existence we suspect only in certain forms of sleep — those rare dreams beyond dreams which come never to common men, and but once or twice in the lifetime of imaginative men. The cosmos of our waking knowledge, born from such an universe as a bubble is born from the pipe of a jester, touches it only as such a bubble may touch its sardonic source when sucked back by the jester's whim. Men of learning suspect it little and ignore it mostly. Wise men have interpreted dreams, and the gods have laughed. One man with Oriental eyes has said that all time and space are relative, and men have laughed. But even that man with Oriental eyes has done no more than suspect....

Set a pen to a dream, and the colour drains from it. The ink with which we write seems diluted with something holding too much of reality, and we find that after all we cannot delineate the incredible memory. It is as if our inward selves, released from the bonds of daytime and objectivity, revelled in prisoned emotions which are hastily stifled when we translate them. In dreams and visions lie the greatest creations of man, for on them rests no yoke of line or hue. Forgotten scenes, and lands more obscure than the golden world of childhood, spring into the sleeping mind to reign until awakening puts them to rout.

I'm a scientist, not a psychiatrist. I don't believe dreams have a 'real' meaning. They're a physical process, and any 'reality' they have lies in the physical. Freud made no attempt to understand the physical. He felt the key to understanding dream lay in content, and came up with an elaborate system of symbols to explain the images in dreams.

Man is essentially a dreamer, wakened sometimes for a moment by some peculiarly obtrusive element in the outer world, but lapsing again quickly into the happy somnolence of imagination. Freud has shown how largely our dreams at night are the pictured fulfilment of our wishes; he has, with an equal measure of truth, said the same of day-dreams; and he might have included the day-dreams which we call beliefs.

The pleasure of the true dreamer does not lie in the substance of the dream, but in this: that there things happen without any interference from his side, and altogether outside his control. Great landscapes create themselves, long splendid views, rich and delicate colours, roads, houses, which he has never seen or heard of. Strangers appear and are friends or enemies, although the person who dreams has never done anything about them. The ideas of flight and pursuit are recurrent in dreams and are equally enrapturing. Excellent witty things are said by everybody. It is true that if remembered in the day-time they will fade and lose their sense, because they belong to a different plane, but as soon as the one who dreams lies down at night, the current is again closed and he remembers their excellency. All the time the feeling of immense freedom is surrounding him and running through him like air and light, an unearthly bliss. He is a privileged person, the one who has got nothing to do, but for whose enrichment and pleasure all things are brought together.
