In addition to his physiological research he also tested subjects’ ability to see a target hidden from their normal sight. His first subject, Miss Z., was tested in a laboratory where a target was placed on a shelf about five and a half feet above the bed where she lay. The target was a five-digit number prepared in advance by Tart and placed on the shelf. Miss Z. slept in the laboratory on four occasions. On the first she had no OBE; on the second, she managed to get high enough to see the clock, and on third night she had an OBE but traveled elsewhere.

Tart’s second subject was Robert Mon
