Snape dies? OMG SPOILER. That's quite obvious, and of course that "scan" is fake. Show me where JK says it's real.
I love the books, but even I won't deny that some things are predictive. Snape will die protecting Harry. We'll finally get confirmation that yes, he loved Lily, and that's the reason he mistreated Harry; Harry is a physical representation of Snape's weakness (his heart) and failure (James was able to "win" Lily, despite being an ass).
