Chiromancists do it with drips. Deja Vu's just think they did it. Rune readers do it where the stones grow. Paranormalists aren't sure how to do it and are contacting Art Bell on the mothership now. Dowsers do it diviningly.
Clairvoyants do it within sight.
Psychometrists do it with feeling. Channellers do it with guidance. Magnetic healers do it with non-fatal attraction. Hypnotists do it in their sleep. Mystics do it in Altered States.
