I think this is really about the actively made decision to spend longer with each sensation than you 'normally' would - relative to your own individual baseline. Basically whether this is a tool in the person's metacognitive toolkit that they typically use or not. Like 'the feeling of the touch of a thought' on the mind itself, as opposed to a linear pre-simulation of a performance to play out loud. Or the difference between making what you say out loud a cheap, low entropy, lossy encoding of all that you're thinking, versus gathering all the aspects quietly and needing to find a way linearize all that incidental complexity.
