Carl Jungs lost twin sister in the Red Book

Carl Jung sat in his study it seems, and induced a kind of waking dream in which he explored his deepest unconscious. He wrote the whole thing down as a personal illustrated journal in a red leather-bound volume - hence the name.

The New York Times reported this today. It seems that during his inner journey

Jung travels the land of the dead, falls in love with a woman he later realizes is his sister, gets squeezed by a giant serpent and, in one terrifying moment, eats the liver of a little child. (“I swallow with desperate efforts— it is impossible — once again and once again — I almost faint — it is done.”) At one point, even the devil criticizes Jung as hateful.

I wonder how long it will take for the Jungians to realise that this is all a pre-birth memory and includes a lost twin sister?

The snake may be the umbilical cord and the liver is the placenta, all that remains of an identical twin perhaps?

Interesting.
