This week I'm experiencing something similar. I hear a voice in my head clearly but it's not mine and can come out of the blue. It always seems to focus on death and urges me to kill myself, whether it be driving the car into a poll or cutting myself.

I don't know if it's an intrusive voice or a psychotic voice, but either way the doc increased my meds.

I also have this thing where sometimes I think people can read my mind and then I argue with myself that it isn't possible.

Good luck I hope it gets better for you.
