Do you ever just have a blank mind?
I.e. In the course of the day, or during conversation, does your mind just 'go blank'?
This is a common occurrence for me. It doesn't trouble me, though it can make conversations a little awkward at times for the other person haha. I usually just say: sorry my mind is blank, I'd say something if I had something to say. At least that's something. It's a blankness of mind that dominates, whilst after an interval I then begin a mental commentary - a narration voice over if you will - like one who walks into an empty room... "So... my mind is blank ey, what can I say... okay, still nothing... there's no movement at the station... I'll just wait it out or wait until they say something I can latch unto."
Hence here I am drawing a distinction between conscious higher cognitive processing and what one might call lower cognitive processing - experientially, they're both tangibly different in a very clear and distinct manner. Perhaps the terms active thinking and passive thinking descriptively help. All of these terms might be used with slightly different understandings attached in the scientific and psychology field, than I am using them here, but perhaps people can relate (or not) to the blankness of mind I am describing. Bearing in mind I am not speaking of a state of mind I bring about through conscious efforts, i.e. It's not a result of eastern style meditation, it is just a natural phenomena/occurrence in my daily experience - it's never disabling or disorientating, quite the opposite really, though socially awkward at times, and it's too hard to say 'how long' such 'episodes' or moments last, but never too long, and sensory or mental stimuli can get me out of it.
