In a way, we think of dreams as (1) either an escape from reality or (2) a reflection/manifestation of a higher (i.e., inner) reality that may or may not be openly acknowledged when awake. I think both ways of looking at things applies to SNIT, when Ennis escapes his self-conflicted nature for a brief moment of freedom, and as a manifestation of a deep acceptance within his part of the reality of love, no matter how/what he feels about that love.
