I AM SCREAMING (@ hp conspiracy theories)

check out this thread (and the many like it) 

I usually prefer canon only, but these are such good analyses ( like Gryffindor = royalty lines of Arthur, foreshadowing/recap of the series in the 1st and 7th books)

these are my favorites

anyways, some of these can be far-fetched and otherwise proven, but still good conversation/thought starters!
