J.W. Dunne

British aeronautical engineer who wrote An Experiment with Time (1927) — arguing that dreams give access to future events (precognitive dreams) and that time has a serial structure (time 1, time 2, etc.) that accounts for precognition — one of the most widely read books on time and dreams in the 20th century.

Proposed serial time theory — regular time is observed from a second time, which is observed from a third, etc. — as the metaphysical framework that explains precognitive dreams without violating causality, and provided the most systematic empirical methodology for documenting one's own precognitive experiences.
