Dreams - Do they have Meaning?!!!


Every person on earth dreams every night – every mammal in fact. It follows then that something extremely important must be going on while we sleep and dream, yet in the industrialized world, the majority of people pay little attention to dreams, and sometimes shortchange themselves on sleep because it is perceived as lost time, or at best unproductive.


How astonishing that we generally ignore this third (and possibly far more) of ourselves. An appropriate analogy to the grandeur of this mass misunderstanding is the incredible inertia in the middle ages against the idea of earth being other than flat until repeated point-blank evidence like Galileo’s observation of other planets and their moons and the journeys of Columbus and other explorers across the ocean proved conclusively otherwise. The challenge was that people’s everyday experience contradicted the idea of a spherical earth because nobody had yet gained perspective from outside of the system. Airplanes and especially photographs from space were not yet available, so there was little first hand evidence of a new paradigm that was quite a great leap beyond the old. Fortunately, people eventually began to come around, and the shift triggered an ensuing surge of exploration as the realization and acceptance finally dawned that our world really isn't flat after all.


Dreams, in the same way, encompass yet another entire dimension of experience, a world as yet unexplored by most, where a fascinating sphere of activity awaits investigation and possible harvest for greater fulfillment in waking life. The challenge is again the same — common daily experience for the average person offers little proof of this other reality, let alone the possible value of this other dimension of experience, unless one can gain perspective from outside the 9-to-5 work day framework and a scientific purely-objective system.


Dream related mental skills such as dream recall or dream interpretation and information on subjects such as the meaning of nightmares or precognitive dreams isn’t often taught in our schools, and the majority of our parents knew or passed on little about the value of dreams as we grew up. So it's no big surprise that many adults remember few or no dreams, and even more rarely contemplate or set out to interpret the guidance and mine the jewels of creative inspiration hidden just below the surface of consciousness in dreams. Basically, nobody told us or showed us how dreams can be extremely practical.


The result of where this long-standing trend of disregarding dreams has brought society is that the current misguided concepts about the value of dreams are not only crucial misunderstandings, but also represent and even bring about a lack of connection with the subconscious and our own deeper nature. This artificial rift may indirectly, or even rather directly be the source for many of our current personal, cultural and planetary social, political, and environmental challenges.


One solution towards rebalancing and integration on a personal and eventually a planetary level, is for each of us to realize and begin to investigate how our personal dreams, at very least, each night offer a direct means to explore inner reality and gain unique, undeniable experiences of deep personal value. Further, there is overwhelming evidence that they can be applied in many ways to improve waking life, supporting Shakespeare's age-old claim by MacBeth that sleep and dreams are the "chief nourishers in life's feast". Dreams do indeed offer opportunities for fun, adventure, wish fulfillment, creativity, deep personal insight and healing — and dreams offer all this at no cost and with no line-ups!

I Have a Dream!!!!

Every one in these life have dream that they want to acheive, also me. My biggest drem is to be a computer engineer. Becouse i like working with computer and i want to know every thing that a computer contain.

What about you my "friends"?

What is your "dream"?

DREAM

Dreams are the images, thoughts and feelings experienced while asleep, particularly strongly associated with rapid eye movement sleep. The contents and purpose of dreams are poorly understood, though they have been a topic of speculation and interest throughout recorded history.


There is no universally agreed biological definition of dreaming. General observation shows that dreams are strongly associated with rapid eye movement (REM) sleep, during which an electroencephalogram shows brain activity to be most like wakefulness. Participant-remembered dreams during non-REM sleep are normally more mundane in comparison. During a typical lifespan, a human spends a total of about six years dreaming (which is about two hours each night.It is unknown where in the brain dreams originate, if there is a single origin for dreams or if multiple portions of the brain are involved, or what the purpose of dreaming is for the body or mind.


Stages of sleep
When the body decides that it is time to sleep, neurons near the eyes begin to send signals throughout the body. According to
J. Allan Hobson, these neurons are located in such close proximity to neurons that control eyelid big muscles that the eyelids begin to grow heavy. Glands begin to secrete a hormone that helps induce sleep and neurons send signals to the spinal cord which cause the body to relax




Discovery of REM

In 1953
Eugene Aserinsky discovered REM sleep while working in the surgery of his PhD advisor. Aserinsky noticed that the sleepers' eyes fluttered beneath their closed eyelids, later using a polygraph machine to record their brain waves during these periods. In one session he awakened a subject who was crying out during REM and confirmed his suspicion that dreaming was occurring. In 1953 Aserinsky and his advisor published the ground-breaking study in Science.
In 1976, J. Allan Hobson and Robert McCarly proposed a new theory that changed dream research, challenging the previously held
Freudian view of dreams as subconscious wishes to be interpreted. The activation synthesis theory asserts that the sensory experiences are fabricated by the cortex as a means of interpreting chaotic signals from the pons. They propose that in REM sleep, the ascending cholinergic PGO (ponto-geniculo-occipital) waves stimulate higher midbrain and forebrain cortical structures, producing rapid eye movements. The activated forebrain then synthesizes the dream out of this internally generated information. They assume that the same structures that induce REM sleep also generate sensory information.
Hobson and McCarly's 1976 research suggested that the signals interpreted as dreams originated in the brain stem during REM sleep. However, research by Mark Solms suggests that dreams are generated in the
forebrain, and that REM sleep and dreaming are not directly related. While working in the neurosurgery department at hospitals in Johannesburg and London, Solms had access to patients with various brain injuries. He began to question patients about their dreams and confirmed that patients with damage to the parietal lobe stopped dreaming; this finding was in line with Hobson's 1977 theory. However, Solms did not encounter cases of loss of dreaming with patients having brain stem damage. This observation forced him to question Hobson's prevailing theory which marked the brain stem as the source of the signals interpreted as dreams. Solms viewed the idea of dreaming as a function of many complex brain structures as validating Freudian dream theory, an idea that drew criticism from Hobson.



Dreams and memory


Eugen Tarnow suggests that dreams are ever-present excitations of long-term memory, even during waking life. The strangeness of dreams is due to the format of long-term memory, reminiscent of Penfield & Rasmussen’s findings that electrical excitations of the cortex give rise to experiences similar to dreams. During waking life an executive function interprets long term memory consistent with reality checking. Tarn ow's theory is a reworking of Freud's theory of dreams in which Freud's unconscious is replaced with the long-term memory system and Freud's “Dream Work” describes the structure of long-term memory
