I had that and it went away as soon as I started taking mood stabilisers...

Kinda miss it as I had three strands of internal thought, the upper, boring me nd the nasty downer me. Now I just have boring me . I doubt your doc would worry about it unless its upsetting, I think it's pretty common.

Ironically I started hearing my name being called when anxious/down when I started taking antipsychotics
