Improve your ghosthunting skills by learning to communicate with the entity through the use of dowsing.
Dowsing for ghosts during an investigation can reveal critical information about the haunting. Both animate and inanimate objects have energy fields. Everything that exists in the universe is ultimately pure energy that gives off a vibrational frequency. This would include every particle, thought, word, emotion, object and experience. When you dowse for a target you tune into its frequency. The response from the rods or pendulum means you are reflecting energy back to yourself for interpretation.
