I used to take very high doses of sertraline for treatment-resistant chronic depression (I'm fine now, thank you), and would often confuse dreams and reality. Sometimes in mundane things, like I'd think the microwave had something in it, or I'd forget the time of day. Other times I'd think I was injured, or someone had died or was dying. It was honestly the most awful period of my life, mentally, and very nearly pushed me into a psychotic episode. This chapter gave me a very primal sense of anxiety recalling that period of my life.
