Mysticism and Psychosis: Descriptions and Distinctions Michael McGhee

. . . spiritual or mystical experiences are those states in which the form of experience is altered from normal consciousness, resulting in a new understanding of the basic nature of reality, life, and the individual. Psychotic experiences are those states that also flow from alterations of the form of experience, but result in a pathological interaction between the individual and the world. Therefore, according to these definitions, phenomena occurring in a spiritual context may be identical to those traditionally viewed as symptoms of psychosis, but cannot be seen as psychotic in themselves.
