I think it flows well from The Gash, but its kind of hard to explain shortly, because it was a complicated trip, but in the shortest version possible, in The Gash, a man faded into his own imagination, and then discovered that that's all life was, this cycle of his own mind, and he was the only real human, if he indeed was real. So, Feeling Yourself Disintegrate fits perfectly. His denial is weakening (how can I live without love, when I'm the only person; how does my life exist without death?), but then he just succumbs into his mind (feeling himself disintegrate).
