During that period I spent an unhealthy amount of time alone. I also spent tons of time reading. During that time the ability of my brain to free-associate seemed to absolutely explode. I felt like I could see a pattern or form a connection between almost anything whatsoever. I read symbolism in everything. The few times I did see friends during that time, I remember them being kind of shocked at the callbacks, linkages, etc. that I was able to fire off instantaneously at the board game table.
My brian no longer works like this. I underwent several lifestyle changes and it seemed to really rewire me. I'm much more logical in my thinking now, but it's taken practice, and the shift was gradual. Every now and then I kind of miss the "semiotic aptitude" I had in those days, but I wonder if I was really just teetering on the edge of a cliff. Maybe a few more months of isolation would have pushed me over the edge.
