Have no Expectations in regressions therapy.
When I speak to clients before our session I emphasize that they do not hold expectations about what will happen in the session.
You may experience a past life, a parallel life, a being a rock, lifefe as an animal, life on another planet, another type of life other than human, pure energy, a future life, current life, or no scenes at all. Having expectations leads you down a false path, letting scenes happening your minds eye is the cleanest slate you can have to begin with.
