table turning, n.All

Table-turning (n.) swept ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠Europe as an epidemic in the 1850s; hardly a party ended without guests slipping off late to question the table.

Table-turning (n.) was ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the parlour game through which a fifteen-year-old girl in Jung's circle discovered she was a medium, delivering grave messages in a pastoral tone from "spirits" of dead relatives.

Table-turning (n.) can ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠be induced in most normal people with patience, as a partial hypnosis confined to the arm; Jung showed it worked by gradually mounting auto-suggestion, not deliberate pushing.
