My husband and I spend some time in home office. He likes to watch videos about how to build your own sailboat while I like quiet, so he uses head phones to listen to these videos. But he had to take one hearing aid out and put an earphone from the headset into one ear.. SO he's sitting with one hearing aide in one ear, one earpiec from the headset hooked up to his computer, andwhat is then the unused earpiece just lying on his desk. Thae earpiece is alive and well aand broadcasting but not very loud, so it sounds exactly like: (1) an aural hallucination; (2) a real conversation between folks who might be walking down the sidewalk in front ofour house. I have other ways to do reality shceks on sounds. If it sounds exactly the same, no matter where I am, then it's probably an hallucination; if it gets louder and louder when I walk in one direction or gets softer when I walk in the opposite directionit's pobably a real sound. Some hallucinations are so preposterous that it's easy to tell they aren't real ---lke when I could hear a men's choir singing just below the window of my hospital room, it's 2 am and raining, and my hospsital room is in Potsdam, Germany, and when the singers stop singing and start chatting and I can detect the the rhtym and cadence of the speech of folks who spent their formative years in east Texas, I'm pretty sure I'm hallucinating them. 😉
