hi,
i couldnt help but notice something in your dream which i heard from joseph campbell in one of his lectures,
namely the two aspects of the buddha
,i dont think the unconscious self is bothered what religion you follow and will use whatever symbology is needed to get the message across.
the two aspects mentioned goes like this,
if you are open minded enough,the peaceful aspect comes,but if you are clinging hold of the ego and its little world,the wrathful aspect comes,
there is also the grail version,
if you are again ,open,the grail maiden comes,she is friendly ,but if you are clinging on to your ego world,the hidious damsel comes,she will tear strips off you,berating you for your sins,
the esential motive in most myths of this theme is to move you on,from some sort of spiritual rut , limbo,stagnation etc
shiva & kali would seem to represent the same duality in the above myths,so dont be offended by this symbology,
hope this kick starts something for you,if not ,i am sure others may trigger something for you,
