Off topic, i just learned that some people hear a voice in their head when they’re thinking or reading.

I don’t think that’s off topic, it sounds as if you don’t have an internal voice which is the audio-form of aphantasia. My inner monologue is ever-present, and often takes the voice of whoever I’ve been talking to recently, especially if I’ve been bingeing a series or just watched a film. Having Morgan Freeman as my inner narrator was awesome, but as you can prob guess it’s a curse as often as it’s a blessing. When I get an earworm it can last for days.

It is hard trying to imagine the absence of something that you have. Like trying to think up a new colour.
