The broad definition of consciousness is our subjective experience of the world and ourselves. It is our ever-changing awareness of the world, also including our thoughts, emotions, and sensations.
Not only is the definition very broad, but the number of alterations of consciousness is very large as well. In fact, across a typical day we experience a great number of altered states in our consciousness. Theses changes range from small to profound.
These alterations can range from working to solve a math problem to having an out of body experience. Other profound alterations include hallucinations, Déjà vu, mystical, hypnosis. Drugs can bring many of these alterations on.
This got my curiosity going, because if we have found drugs such as Lysergic acid diethylamide, and Methylenedioxymethamphetamine, which alter consciousness with the onset of hallucinations and psychedelic experiences, then maybe someday we will have a drug that gives us complete awareness and focus. Most importantly though, I have become aware that consciousness is a loosely defined subject that I hope to learn more about, and hopefully will have a greater knowledge of 5 years from now!

Consciousness is an abstract category having own memory on the basis of our emotional condition and practical experience. It, however, stays comparatively unexplored territory- still, there is one trustworthy explanation what dreams are, are they projection of our fears, hopes or of our subconsciousness?
