I agree with Raspberrytorte, this sounds like a spiritual belief. If your believe does not cause you negative consequences, then I don't see why you'd need to discuss it with your doctor.

when I'm "unwell" I feel I can read peoples minds in a way, and tell their intentions via body language. When I"m "Reading minds" It's always very horrible, negative stuff. So this is not healthy for me. Your situation sounds different.

Let us know what you decide. (To tell your doctor, or not to tell)

Best of luck.
