As sunset approached

A frustrating day at work, leavened by talking with a young man with severe psychosis, and finding he is enough improved already that he considered seriously my suggestion that managing those experiences can be helped by thinking that they occur when the brain gives the self an incorrect message, meaning the psychotic experiences while real (he is experiencing them), they are not true. Not an easy concept to grasp especially when we believe that our brain only gives true messages. Why would I think it’s not true?
