The Ghost Trance is a state of being utilized by Witch Doctors. They train their minds to perceive the Unformed Land through a combination of rituals and the use of select herbs from Teganze. The Ghost Trance allows a Witch Doctor to spend minutes in the Unformed Land, while only seconds pass in Sanctuary. While in the trance, azure light shines from the Witch Doctor's features.
For lower ranked Witch Doctors, it is forbidden to engage in the Ghost Trance following an Igani Bawe. According to the high priests, doing so disorientates the souls of recently sacrificed tributes (a falsehood, as the case is).
