I had a dream this morning (the 3rd i recalled), where I was at work, and was given some coins...I proceeded to try and count them, as you do.
it wasn't a LD...
now, working in a video store, I count money all the time; also being a Math/Finance student, i know i can count! I knew what the coins were supposed to add up to ($19.10), but i couldn't add them up when i tried!!

i tried putting them on the desk, counting one at a time, 2 at a time, but my brain just could not focus or grasp the prospect.
it led me to think...Ive never (that I recall) partaken in simple practical activities in dreaming (counting, reading, cooking and such) at least not successfully.

does anyone think that a dream state may involve primarily perception and sense of the world you are in, rather than letting you utilise your brain for such practical purposes.

ie, is it more for wandering around and experiencing things, rather than actually doing things, as it were.
