sam died 6 months ago at the camp when he was stabbed in the spine.

Dean, you and Bobby have been grieving differently. Dean of course grieved with anger it was his little brother. He was finding any way to recover him, Bobby his was sadness and acceptance. He was sad and depressed. You? Yours was denial. You have kept dreaming about him. Any kind of dream. Nightmares to dreams about him growing up with little kids. This dream was no different. You and him were dancing in an apartment.
