Who is Ivan and how is he linked to the strange dream murders? [Dreambound part 5]

Today we're checking out more Dreambound! The timeline jumping back and forth is making it a little hard for me to keep up, but I'm very captivated by the storyline. Back in the present, we get to know the mysterious Ivan, a little better. He's very criptic but after much probing, he admits he can also enter dreams the same way Noah can. Kaine comes over to ask Noah about My Floyd's dream, but they get intterupted by Ivan. Noah, wanting to know more about Ivan, tells Kaine to leave in the hopes of understanding more about the strange killings that are somehow linked to dreams.
