Jumping- free running????

bizzare epic dream flitting between jumping-free running? around (what is the name of people jumping from building to building in a city?) to wrestling an a Greek gentleman, to love story that involves many lovers- the main protagonist ends up alone at the end, but he's fairly philosophical about it; in fact, a cool song arises from it, 'we can't go on hiding are mismatched intentions under the 'guise of sexual tension..'

dream born through nose clearing itself of a cold 'n' sneezing
