(For those of you who've yet to find someone that means everything to you, put in place your dream lover. ) Say that the person you love is gone. You wake up one day, and they're not in bed beside you. You pick up the phone and their contact list ceases to exist. You ask around and no one has a clue who you're talking about. You've realized that they seem to be a figment of your imagination. How do you react? What do you do?
