This reminds me of two mind-boggling discoveries I’ve had about the human mind. The first is that the two halves of your brain act somewhat independently. And in rare cases, people’s left and right halves are “split” apart, and they act entirely independently - e.g. their left and their right hands will act separately, or even argue with each other. CGP Grey made a great video about this: https://www.youtube.com/watch?v=wfYbgdo8e-8 https://www.youtube.com/watch?v=wfYbgdo8e-8 The other is that most people have a “voice” inside their head - e.g. when they read, they hear their own voice inside their head reading; their thoughts are like sentences they “hear;” they could look in the mirror have a conversation with themselves. Some ~10% of people do not have this internal monologue. https://news.ycombinator.com/item?id=22193451 https://news.ycombinator.com/item?id=22193451 https://news.ycombinator.com/item?id=11162927 https://news.ycombinator.com/item?id=11162927
