J.W. Dunne's 1927 book arguing that dreams give access to future events (precognitive dreams occur regularly but are forgotten on waking) and proposing serial time theory as the metaphysical framework that explains this without violating causality.

Provided the first systematic methodology for documenting and verifying precognitive dreams — Dunne's dream diary method and statistical analysis of time-displacement — and the serial time framework that influenced J.B. Priestley's plays and later precognition researchers.
