Hello everyone

I've been having this experience for some time now. Sometimes I hear a very faint, barely-there voice. I do not hear this voice in my physical surroundings. I hear it in the same way most people do when they experience an earworm (a song stuck in one's head), if that makes sense. It's isn't loud at all, and if I'm in a really busy environment, I don't notice it at all. It also isn't there all the time.

The voice never says any full sentences or even words. Usually it's just odd sounds in reaction to the things I do. It usually sounds like a snicker, or a gasp in surprise, a light giggle or an exhaling sound. 

The voice will make these sounds when I do activities like reading, and I read over a specific word or phrase. Or if I'm writing, or if I'm just thinking quietly to myself. For example I was reading a new book for the first time and I came across the word "calling" and "called" and there was this very faint chuckle when I read that.

The one and only time I ever heard a full sentence was when I met a guy through a mutual friend for the first time. We were just talking in a friendly sense. I heard a very faint voice saying, "He doesn't have a job!". I didn't think much of it. I asked the guy what does he do for a living, and he said to me "I actually don't have a job." According to him had just finished college and was on the job hunt.

Sure by all means that was a coincidence. But I feel really weirded out. It's like someone is in my head with me. I feel like I don't have privacy of the mind.

I do take Risperidone. I'm fearful of increasing my dosage because the last time I was on a higher dose I had gained a lot of weight and I my blood pressure was very high.

Does anyone have experience with this?
