This is incredibly interesting, and honestly, I've wondered this before. For example, I've studied pictures of people before in hopes of creating more accurate representations of them in dreams. That got me thinking that you might subconsciously know exactly what someone looks like. Sometimes I can't remember the details, but then I thought that I must know what they look like because I always recognize them. Good to know!
