How is it that I am able to see someone or a someplace with such detail without actually being there? I know it obviously can't be with my eyes, and I assume it has to do with my memory, but how is my brain able to produce an amazingly accurate image to my conscious mind without me looking at that thing at the time? Also, does this have any similarities to the way I can vividly see something when I dream?

When you "see" something, your brain is interpreting information that is coming in from your eyes. It is not like a video tape, closer to digital, but chemical instead of electrical. The brain stores these images in the form it interprets them. The brain is also very selective in which information is stored or it would be overwhelmed with too much information. It does not store all the information coming into your eyes. Only a very small portion that is deemed important. As when you focus on one little thing and "see" nothing around it.
When you remember something visual, the brain brings that image back to the fore from what has been stored. And, yes, that is the same thing happening when you see vivid images in dreams.

Well when you look at something you brain make a copy of it in you head with chemicls and stuff like that. When you recall that image you brain repoduces the same chemicls and stuff to produce that same image.
