Animagikat:

In ss/ps, Harry has a dream of Quirrell's turbin telling him to 
transfer houses, then forgets it when he wakes up. 
Do we believe in coincidence's? I don't. Not where J.K.R is concerned.
I don't believe he would have 'dreamt' it, if it wasn't possible.

As for the pensive, it would be interesting to see who else's brain 
has too many thoughts crammed inside. IMO, the diary in CoS seemed 
like a sort of Pensieve. If a 15 year old orphan has that magic at 
his disposal, like Riddle did (Yes, I do realized I'm talking about 
the most evil wizard in a century), It must be somewhat common. At 
least nothing Hermione couldn't find given ten minutes alone in the 
restricted section.;0)
