I was about to set the needle on an LP record track (kids, ask your grandparents) when, just before the needle touched down, the right-hand speaker very clearly said, “Cheeseburger.” I was so surprised that I turned to the speaker and said, “WHAT?” It did not, thank dog, repeat itself.
This is as close to a supernatural experience as I have ever been. Other people have told me they saw ghosts or spoke to god. I heard my stereo component request a cheeseburger. As supernatural experiences go, it was startling at the time but I would have to rate it as totally underwhelming in the great scheme of things.
