text: Snakes (in western civ. and Freudian psychoanalysis) usually symbolize sexuality, temptation and possible corruption (the whole Garden of Eden thing). \n\nThe underground part symbolized either the womb or the underworld (the "bad place"!). \n\nI think dreams are one of two things, or often both: the reliving of our waking pursuits and thoughts AND symbolic of our needs, desires, fears and so on.\n\nPerhaps your father's presence (usually an indicator of an authority figure) symbolizes the need for you to drive the serpent (sex and/or temptation) out of you. (Is your father very religious?).\n\nBeing crucified  is more a wish for those raised to admire Jesus (he died, yes but but was supposedly resurrected AND then worshiped!). You may feel you have greater things in store for you, that cannot be achieved in this lifetime, only by martyrdom.\n\nAccording the the Jungian based site: "The universal hero myth always refers to a powerful man or god-man who vanquishes evil in the form of dragons, serpents, monsters, demons, and so on, and who liberates his people from destruction and death."\n\nHowever, since the father is crucifying you, the ability to act as saviour is impeded.\n\nOn the third link (levity.com), there is a semi-humorous interpretation from (East) Indian mythology involving turning into a snake as a type of crucifixion (???!). \n\nI'd work on THAT aspect! Good luck!
