Kaboom (2011)

Smith, a typical young college student who likes partying and engaging in acts of random sex and debauchery, has been having some interesting dreams revolving around two gorgeous women -- and is shocked when he meets the dream girls in real life. Lorelei looks just like his fantasy brunette, while a mysterious red-haired girl being chased by assassins draws him into an international conspiracy. Or is it all just a drug-induced hallucination?
