The Answer to the riddle is me

In 2002, at age twenty-eight, David MacLean "woke up" in a foreign land with his memory wiped clean. No money. No passport. No identity. Taken to a mental hospital by the police, MacLean then started to hallucinate so severely he had to be tied down. Soon he could remember song lyrics and scenes from television shows, but not his family, his friends, or the woman he loved. All of these symptoms were the result of the commonly prescribed malarial medication he was taking. Upon his return to the States, he struggled to piece together the fragments of his former life in a harrowing, absurd, and unforgettable journey back to himself.
