You say that an emotion is the mind's reflection in the body. But sometimes there is a conflict between the two: the mind says "no" while the emotion says "yes," or the other way around. If you really want to know your mind, the body will always give you a truthful reflection, so look at the emotion, or rather feel it in your body. If there is an apparent conflict between them, the thought will be the lie, the emotion will be the truth. Not the ultimate truth of who you are, but the relative truth of your state of mind at that time. Conflict between surface thoughts and unconscious mental processes is certainly common. You may not yet be able to bring your unconscious mind activity into awareness as thoughts, but it will always be reflected in the body as an emotion, and of this you can become aware.
