ASK A QUESTION
When I look at the room I'm sitting in, I am consciously aware of it as existing outside my body and head. So, for example, I can walk towards the opposite wall and I appear to get closer to it until I reach out and touch it. Now I understand that light is being reflected off a wall, travelling across a room, entering my eyes and this process creates nervous impulses. (In fact a physics would correctly point out that the photons that hit my retina are not even the same as the photons 'reflected' by any object). I understand that these impulses are processed in various parts of my brain, some unconsciously but eventually a mental "schema" representing the room is created. I also understand that there are other processes going on in my brain that create my awareness of different types of "self"s, that continually shift my awareness and that attempt to always produce a self-consistent view of myself and the world. However, my question is not about these (well not directly!).
