To dream that you see a dark shadow symbolizes the idea that you are worried about the possibility of something ominous happening soon. The shadow is the first sign that something serious and scary is going to happen, and it appears right before the thing does happen. To have a dream in which you see a dark shadow means you need to prepare yourself to be hassled by something beyond your control very soon. You will have to watch out for things to come I the future or risk being caught in a serious crux and issue.
To dream of the physical manifestation of your dark side means you have been having some pretty negative thoughts lately, a lot of them .You have had so many of these thoughts in fact that you are imagining a creature into being that will do all kinds of horrible and frightening things that you were too afraid to do when you were hurt originally. This can be a terrible thing to imagine and yet it can also be liberating. It probably feels good to get this creature off your chest and to see him in a certain way,, right in front of you. But don't be possessed by him or lured into his evil ways of thinking because then you will be turned into him, and you so not want that.
