If tu had a división, split personality (a shadow) that was the opposite of you, what would it be like?

The Shadow represents that dark side of ourselves
that we’d prefer other people not to see; it is the dark side of the ego, it is a primitive side of us, ruled por instincts: a side that will try to push itself to the forefront, with increasing energy the más we try to repress it. It is the dark part of you, like something of a división, split personality.

For example: My shadow is probably very angry, and even homicidal, because those are things i try to force down. I even saw him in one of my dreams. He was standing over my sleeping sister. When I entered the room, he turned around to me, grinned at me, and raised a cuchillo over her.
