In Philip K. Dick's book "CHOOSE," the protagonist begins to keep a journal, a secretive habit that hints at his unstable state of mind. This act of writing becomes a way for him to process his thoughts and emotions, but it also reflects a deeper sense of paranoia and confusion that he grapples with. The description of his journaling suggests that he feels compelled to document his experiences, even if it seems peculiar to others.

This behavior illustrates the struggle between the desire for self-expression and the fear of being misunderstood or judged. The journal serves as both a refuge and a source of turmoil, hinting at the protagonist's internal conflict. Ultimately, Dick uses this motif to explore themes of identity and reality, showcasing how one person's private actions can reveal profound insights into their psyche.
