It's normal to play the same song over and over again (2016)
I'm terrified of this. I've no idea why, but if I hear a song too many times in a couple day period I have a night of fever dreaming where I wake up over and over again to the song in my head. It's like my brain has over conditioned the pathway for that song and as soon as it starts trying to dream it falls into it and the dream breaks and I wake up. It happens to me a couple times a year and when I hear any of the songs it's happened with before I feel a deep physical revulsion.I kind of wonder if it's a symptom of something but am otherwise more or less 100% neurotypical so I think it's just a weird quirk.
