Thank you so much!! I am very happy you like this one, I haven't use this medium very often.
When I doing this one I was thinking that I really love them to be happily together. With after the war they couldn't find Snape's body that Harry still thinking about him. And after Occlumency lesson they have in fifth years, that might created some connection, and use dream as medium to find each other without the boundary (time or space)...That is what I feel at that time. :)
Thank you again and sorry about the late reply...
