I just finished reading a book by Aldous Huxley called "The Doors of Perception" (awesome book btw) and it got me thinking. Consciousness is the result of a chemical balance in the brain and thus creates our perception of "reality" (whatever "reality" really is). Drugs such as cannabis alter this chemical balance resulting in an altered perception of reality. This makes me think. What if consciousness itself is really a drug trip? What if everything we experience is not really real, but rather just what our current chemical state of mind allows us to perceive? What if drugs actually allow us to bypass the "perception filter" of consciousness thus allowing us to experience other realities equally valid as our normal conscious reality? What if life and reality itself is one big drug trip?
I myself believe that life is one big drug trip. Emotions strongly contribute to the foundations of our reality and have been scientifically shown to be the result of chemical activity in the brain... that is they are caused by drugs. Why can't this be the same for everything else?
Anyway what do you guys think?
