Our dreams are usually altered and changed by what we see, stuff we saw that day often find there way into our dreams, not uncommon is people we see everyday but often might not realize we notice or register, like kind of like when you walk into a room you may see lots of people but you may not see all there faces or something you know they are there but you don't directly see them.
