Interesting. In your daily activities, you cite your mind as 'clear' -- is it just of visual imagery/sounds, or in general? Do you 'feel' thoughts some other way? What is going on when you 'zone out' in your mind? Say for a programming problem, If you don't see code in your mind, do you still 'feel' it some other way?

Can you describe what you experience when recalling something?

For me, (it of course varies by the object of recall) it is most times imagery, although sometimes it can be emotions, sounds, etc. (I use the imagery as an 'address' after which other related memories are linked to and emerge).
