I am currently writing a short story called "My Small Reality" and I need some help.
the premise of the story is the character is the only thing really exists. he is the Alpha so to speak. But parts of his sub-conscious have become sentient as a result of a massive shift in his ideals. these broken of bits are slowly gaining more and more control over his reality. so I need ways to mess with his head and make him doubt reality. But I have no ideas about how to do this and really need some help.
