The Interdimensional UFO Hypothesis: History, Key Thinkers, and Cultural Echoes
To the point
Interdimensional UFO theory says sightings come from experiences of other dimensions or portals that share space with ours, a view advanced by Meade Layne, John Keel, J. Allen Hynek, Jacques Vallée, and Jeffrey J. Kripal, linking contemporary reports to older ideas of hidden realms like jinn and angels and to 19th‑century Theosophy, and it has influenced popular culture such as Indiana Jones and the Kingdom of the Crystal Skull and Interstellar while leaving room for uncertainty.
