He was desperate for u, he still is. He saw u in his dreams as u were practicing lucid dreaming and he was in love with u ever since. He always waited for u to dream to see u again, of course he shapeshifted to not make u suspicious. One day, u decided to stop as u were scared of possibly getting nightmares. He couldnt see u anymore so he decided he'd find ways to seek out to u in real life.
