A few days ago the strangest thing happened, the radio was on in the other room and it was playing country music and I was sitting in a different room checking my emails when a high pitched sound hit my ear (just the left one) and I heard sometime of music and undecipherable talking almost as if someone put a headphone/ear piece right up to my ear. It lasted for a few seconds and then it went away. No one was around me and there were no other sounds in the area aside from the country music but the sound/music I heard was definitely not country music. So where did this music/sound come from? what was it? Thank you.
