The dream metaphors link feelings and emotions with visual imagery. It has been suggested that we dream and heighten this connection with others to survive not as "individuals," but to survive as a "Whole". This would also suggest that when events become catastrophic, or threatening our survival as a species would sense them in our dreams. So what are we doing when we are dreaming? We are correlating data syncronistically (in a Quantum Physical,"space like" separated events) with (classical physical "time like " separated events.)


It is very easy to know and understand that every action (which has its own set of equal and opposite reaction) executed by man force or nature, in this world or beyond, is being carried out due to the presence of the power of science. It is when we grow up that we realize how our Utopian fairy tale world (which as children we knew was held by a herculean force) actually stands, rotates and revolves due to Physics. It seems very nice to think about Einstein sitting in the shade of a tree and discovering gravity or Watt looking at a pan in his kitchen and gifting the world what we call a steam engine. But all these miraculous inventions and discoveries start to seem impossible to decipher when they enter our Physics books and the spirits of those great men haunt us in sleep.


We often necessitate the need for extra guidance in the subject in concern beyond the reach of classroom studies and that is exactly the time when we can opt for experienced tutors according to our respective individual needs. The general theories of Physics include Electromagnetism (including Magnetism, Electricity etc.), Thermodynamics (including heat engine, Kinetic theory etc.), Theory of Relativity (including special and general relativity), Statistical mechanics, Classical mechanics (including Newton's law of motion, Kinematics, Statics, Dynamics etc.) and Quantum mechanics (Schrodinger equation, Scattering theory etc.). Astrophysics, Chemical Physics, Atomic Physics, Biophysics, Classical Physics, Geophysics, Nuclear Physics, Molecular Physics and Condensed Matter Physics are the basic classifications that form the subject from the roots. A few other sub fields are Optics, Thermodynamics, Quantum and Particle.

Our waking awareness is concerned with Space-Time-Matter issues. We organize our daily experiences according to our coordination with Space, Time and Matter. Not so in Dreams. Why would our dreams act this way? Well in Quantum Physics we are also taught the concept that we are all connected. One thought might be that these dreams are assessment damage. While we are awake we are fairly self-centered, individualized and fragmented. During our dreams we seem to rearrange the daily residue of waking life according to different priorities. The dreaming self seems concerned with anything that interferes with it's "connection" with other human and sometimes non-human beings. This is done thorough visual metaphor.

In this new Age of Quantum Physics we are able to introduce the idea of both Quantum Physics and dreams being "timeless."

When we are in a sleeping dreaming state or a having a "Shamanic Experience," particularly when it is taking place in the dark, you are shut off from the outside world and it's perceptions. The dream is a view into the Freudian id or, if you like, the unconscious mind.

Quantum Physics, like dreams does not deal with the "outside" world of matter, but instead with ghostlike clouds of possibilities. To put it in a more understandable way, by controlling these nebulous, possibilities, one gains some control of the "real world." Ordinary or non-telepathic dreams differ from telepathic in one way, and that is the data that is collected during the dream. Ordinary dreams usually correlate the days remembered experiences with past associations and/ or future expectations contained in memories.

But telepathic dreams are very different. They tend to correlate feelings and emotions with space-time events.Dreams seem to originate in a way that escapes our normal waking selves. We tend to dream of things that we may never have even thought we had any concern with. Where as our waking awareness is concerned with space-time issues. This Dreaming effect would be very similar to the high level abstraction of Quantum Physics where there is in actuality no breakdown of Space, Time, Energy or Matter called "S.T.E.M."

Physics covers a wide range of phenomena, from elementary particles (such as quarks, neutrinos and electrons) to the largest superclusters of galaxies. Physics aims to describe the various phenomenon that occur in nature in terms of simpler phenomena. Thus, physics aims to both connect the things observable to humans to root causes, and then connect these causes together.
For example, the ancient Chinese observed that certain rocks (lodestone) were attracted to one another by some invisible force.

This effect was later called magnetism, and was first rigorously studied in the 17th century. A little earlier than the Chinese, the ancient Greeks knew of other objects such as amber, that when rubbed with fur would cause a similar invisible attraction between the two. This was also first studied rigorously in the 17th century, and came to be called electricity. Thus, physics had come to understand two observations of nature in terms of some root cause (electricity and magnetism).

However, further work in the 19th century revealed that these two forces were just two different aspects of one force – electromagnetism. This process of "unifying" forces continues today, and electromagnetism and the weak nuclear force are now considered to be two aspects of the electroweak interaction.

Physics is also significant and influential through advances in its understanding that have translated into new technologies. For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.

Physics (from Ancient Greek: φύσις physis "nature") is a natural science that involves the study of matter and its motion through spacetime, as well as all related concepts, including energy and force. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Certain research areas are interdisciplinary, such as mathematical physics and quantum chemistry, which means that the boundaries of physics are not rigidly defined. In the nineteenth and twentieth centuries physicalism emerged as a major unifying feature of the philosophy of science as physics provides fundamental explanations for every observed natural phenomenon. New ideas in physics often explain the fundamental mechanisms of other sciences, while opening to new research areas in mathematics and philosophy.
