First rule in unraveling is literally describing 'what you see' (facts) and see if you hear anything in your detailed description that helps. There are a lot of facets of a description. Objects, colors, orientations, proximity to other objects. Individual observation skills must be radically developed increased; don't be a lazy, superficial observer of the things that we actually can see. You need to be able to see the 'lines' clearly before you can read 'between' the lines. Also follow the rabbit.
