MZ womb twin survivors - a life and death struggle

If we look at two identical twins sharing a sac, if they are both to survive they must share equally the space, oxygen and nourishment. If that share becomes unequal, then one of them may die.  If one of them dies, the survivor will be left with a sense of being half, not a whole, accompanied by a deep, vague sense that their life and survival came at great cost.

In the Dream of the Womb there is a sense of great vulnerability and being there at the cost of another life, but there is also a sense of it being quite natural to have everything the way you want it and freely exploit and take advantage of available resources.  This is a reflection of the life and death struggle that characterizes the life of two monozygotic twins sharing a sac.
