Secret agent?

So I was so desperate for some clarity I looked in "The Complete Idiots Guide to Psychology" and found that it described our subconscious mind as sort of our "secret agent" which I found to be really interesting. In it the author explained what I have been talking about in the past few posts the whole subconscious stores every thing thing. It also gave an example of people being able to recall conversations doctors had while they were being worked on that they couldn't possibly have known. Of course the methods of getting this information can seem a little sketchy. Hypnosis, I mean, it sounds completely crazy but many people swear to its accomplishments and we must stay open minded so I say why not?
