Actually acknowledging them helps. It sort of takes some of the power away from them. Reality testing. Doing something comforting or soothing. Changing my environment--like going for a walk if the hallucinations are on the walls. Journaling about them. Talking it through with my T but I won't see her until April 15. Praying. Getting distracted by something else that requires a lot of concentration like a puzzle or something. Making myself use the five senses (or several of them) to pay attention to my surroundings that I know are real. Things like that. So I do have some tools to combat them.
