Ive been hearing things...?

scientist have proven that our body reacts to different wavelengths differently. You could have schizophrenia or maybe your just hearing something that can only be heard in very quiet situations, like the neighbor's tv. I had an old turn dial tv that picked up radio stations, maybe that's it. Another option is that you have a vivid imagination. I've been in situations where I know I did or said something, but people will swear I didn't. I must have imagined myself doing it. I wouldn't worry either way. The fact that you realize mentally healthy people don't hear things is a good sign your not crazy.
