Whether you've closed your eyes and dreamed about the guy you saw on the subway, your boss, your ex or Bradley Cooper, those sexy dreams can have an impact on your waking life. All you want to do when you wake up sometimes is shake off the weirdness of dreaming in that way about people who you may never, ever want to (or have the chance to, in Cooper's case) have sex with. Not to mention the mental infidelity that just occurred in dreamland if you're currently married or in a relationship with someone else. Of course your dreams didn't actually happen in real life, but they can have an effect on your relationship, according to a recent study. Researchers published findings of dream studies in The Social Psychological and Personality Science journal, and their findings are somewhat surprising.
