The Time Element (Pilot) from Desilu Playhouse

A man (William Bendix) visits a psychoanalyst, complaining about a recurring dream in which he imagines waking up in Honolulu just prior to the Japanese attack on Pearl Harbor. Rod Serling wrote a teleplay intending for it to be the pilot episode of a new series called The Twilight Zone. Although it ended up airing on a different show, Westinghouse Desilu Playhouse S01E06, it is still considered the pilot episode of The Twilight Zone.
