ok, it is easier to clarify than to conjecture.
just guessing, armed with some of what i know about you. but the cow and the tranquility would seem to have to do with leaving the City, which is often symbolized as dark and cramped yet somehow safe because it is known. It offers protection against nature which can both beautiful and brutal - especially dangerous to someone who doesn't really know nature's ways.
the crow might be the trickster crow - knowing what you need and knowing you must be deceived into taking action. the crow can represent the bringer of great knowledge and the robber of security. He is bigger than other birds and is not afraid to play rough but will ultimately befriend those who befriend him. likewise the leprachaun is a trickster only one who can never be trusted, only tempting for his own gain. he will eventually take back everything he gave if you play his game and you will be left with nothing more than you started with at best. apparently his temptation for you is money.
the reptile thru the rocks - seems sexual enough, but not homosexual. more like frustrated sexual. the perfect round breasts are cold and hard and unaffectionate - perhaps even artificial with their 'perfection'. you see the only way to get near and enjoy them is to slither your way into a position where they are accessible. of course the reptile is cold blooded so the relationship is not emotional from either side, but purely physical and convenient. The relationship is a natural one, neither good nor bad by itself. More important would be how you feel about this relationship. is it enough or is it lacking? is it your pattern or the most reccent situation?
ok, that's my shot at adding stuff. i could be way off but my last bit of advice about how you feel about the interpretations stands. If you feel uncomfortable with any of your own version, then ask yourself if this is something you have trouble facing up to? If you have trouble with any of my version, toss it out the window because it probably is more me than you.
whoa, look at the time. i think it is time for me to go try having a cool dream or 2
