I think you should tell your pdoc, because it sounds like psychosis to me.

edit: Then again, I consider pretty much all of the "spiritual" experiences I've heard people describe to be some form of psychosis. So my opinion is probably in the minority.

edit #2: But also... a condition is only thought of as pathological if it's causing harm or distress. So if you're content with your spiritual experiences, and they aren't harming you, then I guess it would be okay to keep it from your doc.
