Uncontrollable or movie-level happenings are a stupid trope given to humans so that they fear and misunderstand what psychic powers truly are.
You can receive things from the astral, but that does not mean they are good or of the Gods. Always connect and focus on your GD in these moments, and do grounding practices, as well as live your life in the material sense. It's about sanity and becoming accomplished humans, not airheads. If you have these chakra points open and are still doubtful or experiencing confusion, ask the Gods during the Ritual and you'll be given a clear answer.
A Zevist who practices the meditations will understand clearly what is of psychic hearing and what is imagination and harmful. This power develops gradually, under your own control.
