I have just listened to track 9 of disc 2 of the Prelude for the first time. I noticed that it slowly excelerated to the point that I couldn't understand any of it. Out of curiosity I fast forwarded it to see just how fast it was going to get. I noticed that it was slowing down towards the end. So, the middle third to middle half didn't make any sense to me consciously. Is this supposed to be an other than conscious experience?
