You are a Dreamwalker, and Andrew is a Seer. You two had been seeing one another for months, but only when you were asleep. As a result, most people believed Andrew was psychotic - no one but him could see you, he couldn't even touch you as you weren't physically there with him. He slowly started to believe he was crazy, but you told him to not give up hope. You told him to keep on going, to wait for the day you two finally meet for real.
