This is slightly off-topic, but I just wanted to say thank you for writing this article! I never knew people thought/imagined in so many different ways.
Personally, like codingdave, my "milk voice" is my own voice. I can "hear" my voice, with texture, inflection, and everything, as if I were reading my thoughts out loud. The milk voice doesn't have to be my own; I can vividly imagine the voice of anyone else I've heard. I have often wondered about that; how is it that with so little sample data (hearing someone talk for only a few seconds) I'm able to imagine them saying _anything_, with any inflection?
That begs another question - if you are doing something althletic (or even soemthing simple like driving a car), do you develop "muscle memory" the same as other people, or do you need to actually think through each motion you perform?
There was a study done a while back that looked at whether people could improve at video games by imagining themselves playing. IIRC the participants who imagined practicing showed a comparable amount of improvement in contrast to those who actually played. Can't find the link unfortunately.
Similarly I read once that during recovery from a trauma that prevents to do a particular physical activity if one imagines doing that activity, then it shorten the recovery time and leads to less muscle dystrophy.
