Cannot believe the ancient Greeks or Chinese didn't figure out that we had these totally seperate experiences. I first learned about it on reddit. People on both sides were shocked.
The inside of my head is a movie screen. If I have a picture to help me along, I can keep the memory accurate and sharp. My memories are very short video clips, but I can see them clearly. I can picture sitting around the breakfast table after seeing Star Wars, 1977. I can feel and smell the cheap, smooth texture of my parents polyester comforter, when I was old enough to stand up and touch the top.
If I lost this ability, it would be tantamount to being blinded, no idea how I'd cope.
I kinda get how others do without. Sometimes solutions to problems come to me by instinct, gut feeling. Playing Solitaire on my phone I have no real memory of what's in the draw pile, but I "know" there's another red queen in there. But I have to be moving fast, otherwise I stop to smell the roses, look for the picture. Does that make sense? I'm imagining that instinct is much sharper in people without internal pictures.
