I have this, and I know a couple people who discovered they have it too. I think it’s likely more common than people expect. Radiolab did a fantastic podcast about it: https://one.npr.org/i/1254201231:1254201233
I don't see images or hear a voice. Everyone who's one way (sees or hears or both or neither) usually thinks everyone is the same as them but there's a ton of variance. When i learned that some people see or hear, i started asking everyone. It's funny how many people think the voice is god.
Interesting, I’m not sure if I can hear exactly… it’s very different from a spoken voice. I can sort of play music in my head though if I have a song I want to hear but I’m not sure if it’s “hearing it” or just a kind of ephemeral knowing how it goes.
I can "listen" to music in my head, and distinctly make out the specific tone and pitch of the instruments, but I have to concentrate to really hear more than one instrument in the "foreground" if that makes sense. I also have ADHD and probably ASD, so I'd be curious to know if those play a factor in being able to hear your own voice and such in one's head.
I don't have ADHD or ASD but PTSD and used thinking about music to mute intrusive or bad thoughts in general. Now I have a radio in my head I can't turn off...
That does make sense (to me at least), now that I’m paying attention I feel like I can focus on individual instruments or vocals and I am still aware of the others in the background but they’re less prevalent. I also have ADHD, not sure about any correlations there
