No, that wasn't a dream (unfortunately). It was kind of part of a rough night I had that involved uncovering that memory. (Sorry) I guess I was sort of putting it in there to provide a bit of context to the whole...dream I might have had. The dream I did have was thankfully more pleasant than...y'know. Even if my friend and I did end up reenacting that scene from Chamber of Secrets where Harry and Ron crash into the Whomping Willow in that dream.
