Sometimes the barrier between our inner and outer selves gets weak, and we hear our own debilitating thoughts as though they were someone else's. However, it is not possible for others to get inside our heads, although it certainly seems like it! You are not the only one with such thoughts. One thing to keep in mind. These negative thoughts reflect our worst fears and are NOT TRUE! They are lies. I don't know why we deceive ourselves so, but so many of us have these same fears and negative thoughts. Some people even hear them as though they were coming from something external, like the radio or even the thin air. You seem to have insight and to know that something is not normal. I imagine that your DID has something to do with the problem. That might explain the little girl's voice. Be sure and tell these things to your pdoc or T. billieJ
