Reality is defined as the state or quality of being real. Reality is the sum or aggregate of all that is real or existent within a system, as opposed to that which is only imaginary. The term is also used to refer to the ontological status of things, indicating their existence. In physical terms, reality is the totality of a system, known and unknown.
A dream is a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. The content and purpose of dreams are not fully understood, although they have been a topic of scientific, philosophical and religious interest throughout recorded history.
How do we know which is which?
How do we know that the scenario that we have perceived as a dream is actually a dream and what we think of as reality is indeed reality?
Dreams are a manifestation of an individual’s deepest fears, longing, and a variety of other emotions and needs. Reality is just what an individual conceives as being real because there are more evidences and witnesses of the events that happen in that state.
But why is it so?
We have no bases to define dream and reality the way we do.
To be able to do that, one would need complete information on both the avenues. While we know a lot about what we have termed as reality, we have literally no information as to origin, cause or purpose of Dreams!
What if Dreams and Reality are the same but just in different dimensions?
Maybe when one sees oneself flying in a dream, one is merely on the outer reaches of a Higher Dimension but is incapable of processing that thought and incorporating that idea because of the inability of one’s brain which is designed and accustomed to perceive in no more than 3 dimensions.
As someone once said:
Once upon a time, I, Chuang Chou, dreamt I was a butterfly, fluttering hither and thither, a veritable butterfly, enjoying itself to the full of its bent, and not knowing it was Chuang Chou. Suddenly I awoke, and came to myself, the veritable Chuang Chou. Now I do not know whether it was then I dreamt I was a butterfly, or whether I am now a butterfly dreaming I am a man.
