I have minor hallucinations almost constantly myself. Didn't really notice it until I moved out on my own, away from a huge loud household setting, but it's always happened to me. Then again, I'm more often than not in the middle of an episode. Whether I'm depressed or manic, I get hallucinations. I was reading around in the "Schizo & Psychosis" forums & perhaps your disturbances could be derealisation. Perceptory disturbances as a result of stressors. Just talk to a T & try some self soothing methods. Mine usually get really bad to a point where I have to put myself to sleep, but if it gets me in a calm place, it's what I have to do... Take care.
