Basically, information is constantly flowing into me in infinitely rich detail gathered by my senses. I immediately see EVERYTHING that exists in physical form - structures, large and small, and natural forces acting on those structures. I see in real time like a video camera records visual information, except in much greater detail with four additional senses. It's a 3D world that will never be recreated virtually.
Living "in the moment" is about sensing "real" things - sensing that things exist independently from myself, and observing cause and effect. Being alive to me is sensing physical information and then mastering it. The physical world is one huge playground.
Things that don't exist in physical form and can't be sensed are difficult for me to comprehend, so I don't spend too much time thinking about them. The only reason I even have a vague understanding of "feelings" is not from my experience with my own feelings, but rather my experience with other people's feelings. Being able to observe the effect of my actions and words on other people is the main way I experience and understand "feelings". Were it not for social interaction I wouldn't even experience feelings that didn't have to do with my sensory perception.
Spirituality is non-existent to me - atheism is simply the nature of my being.
What does your reality "look" like and how do you experience it? What is "real" to you?
