Trelawney's Prediction

[TL]

No: HPFGUIDX 43991

I don't know how well this floats with all the other theories about
Trelawney's first correct prediction, but I've always assumed that
Dumbledore was present when she went into a trance similar to the one Harry
witnessed, where she doesn't have any memory of what she just said, and that
it fell in line with information Dumbledore already had (perhaps that the
heir of Griffindor would destroy the heir of Slytherin or something like
that), and that's why Dumbledore credited it.

As to Voldemort, I've always assumed that he had his own pet Oracle who made
a similar prediction, thus setting him up for a nice Greek tragedy of
self-fulfilling prophecy (not that I'm implying that Voldemort's seer was
actually setting him up, just that as in early Greek tragedies, the attempt
to avoid fate causes the person to bring about that which he tries to
prevent). Dumbledore's spies or spy could have told him about Voldemort's
seer's prophecy; two nearly identical (and unrelated) predictions would be
far more believable than one.

I hope this makes sense and isn't just a rehash of something someone else
has said (that would be unintentional and embarrassing).
