Easton's 1897 Bible Dictionary:

Trance
   (Gr. ekstasis, from which the word "ecstasy" is derived) denotes
   the state of one who is "out of himself." Such were the trances
   of Peter and Paul, Acts 10:10; 11:5; 22:17, ecstasies, "a
   preternatural, absorbed state of mind preparing for the
   reception of the vision", (comp. 2 Cor. 12:1-4). In Mark 5:42
   and Luke 5:26 the Greek word is rendered "astonishment,"
   "amazement" (comp. Mark 16:8; Acts 3:10).
