This essay contends that Henri Bergson's, Edmund Husserl's, and John McTaggart's examples of duality accounts of time reflect the division of temporal experience in depressive psychosis into objective and subjective aspects of time. The research also suggests using the concept of a dual orientation to reality that is typical of schizophrenic delusions to understand the full-fledged depressed temporal illusion, in which the subjective flow of time comes to a standstill. A person who has a depressed temporal illusion asserts that time is not passing while concurrently maintaining a mostly unaffected cognitive orientation to time, leading to the dual orientation. The depressive hallucination about the passage of time can be located by contrasting temporal experience in depression with temporal disorientation in dementia.
