Hi, @hallieBETH, I started out with the radio sound. I thought it was coming from a neighbor with their window open. Or sometimes I thought maybe the sounds were coming from a school nearby using loud speakers for one of their functions. Then I started hearing music, & again I thought it was coming from someone else's radio. I eventually realized the sounds were coming from inside my own head. After that, the sounds continued to evolve. I think some part of the brain was learning during this evolvement, using memory to imitate sounds, maybe for self entertainment. Thank you for sharing your experience. I wonder how many people hear the radio or tv sound?
