(Psychological / emotional perspective)

In dreams, the hag is variously the cantankerous old woman or that aspect of femininity that aspires to use intuition and understanding for the benefit of her community.

If the former, we need to come to terms with what appears to make her cantankerous in the dream – pain or disillusionment perhaps.

If the latter, then the greek goddess hecate, as keeper of the crossroads, is worth studying.
