Boundaries. It could be that the entities talking to you are beneficial, but you don’t know that, and you must stay sovereign to win this game.
In this case, I suggest you go back to basics and start with learning how to cleanse and banish, and set wards and protections so only those entities you have given permission to work with you are allowed into your energy field. All others will have to contact you through signs and omens, and only the most powerful, like deity, will be able to touch you directly.
This will also help with setting up protection from other human practitioners, random negative vibes from sensitives and crappy energy in your environment.
