You're cool, dude! Definitely not an average person. What you describe is a meditation of a kind (there are many) actually. Have you tried the next level? Given you can silence your inner dialogue/monologue/etc while maintaining awake conscious mind and concentrated attention, "turn around" (your attention) and try staring at the still space that is the background to where endogenous mental stimuli (verbal/conceptual thoughts, images, feelings etc) normally appear, try to find where the point of "you" hides from which you look at all the images thoughts, stare in this direction rather than on a physical object or a thought. It sounds crazy like a camera filming itself without a mirror but it's possible in this realm and feels awesome once you succeed.
Well, thanks! No, I never "turned around", nor do I think that what I described is particularly cool, since it puts some ~ consequences on the way I communicate, like e.g. I'm falling off conversation for few seconds before an answer emerges. But is this next thing safe and pragmatic? Any good read on that? Asking out of curiosity and because I'm not really into that... 'spiritual' thing that accompanies many mind-related areas.
