Yeah, that's more or less how I interpreted it... not so much lag, precisely, as a failure to synchronize. There were lots of weird neural effects that turned up during that time that, on consideration, seemed to basically be timing/synchronization failures, whcih makese a lot of sense if various parts of my brain were changing the speed with which they did things as the brain damage healed and the swelling went down.

Of course, it's one thing to know intellectually that my superficially coherent worldview is the result of careful stitching together of outputs from independent modules operating at different rates on different inputs; it's quite another thing to actually experience that coherency breaking down.
