So I'm at a client and I'm checking mail and some feeds. A normal afternoon other than the location. Hours pass. Then, as I'm doing something completely unrelated that moment replays in my mind. And I was struck by how that stream of consciousness reminded me of something else, which has not yet happened. More how my description of checking mail and feeds and what I was reading at the time which is/was/will be a part of the something else which has not yet happened. Can a memory of a memory be a precursor of a memory of something which has not happened yet? Strange? Now if sleep would come, that would really tease my brain...
