This question already has an answer here:
I've had a look, and while there are many similar questions, they ask about the Marauder's Map or Nagini or some other such magically enhanced object/creature. My question is specifically about Dumbledore, an otherwise ordinary (If very powerful) human wizard.
In Philosopher's Stone, Dumbledore looks directly at Harry and Ron in Hagrid's hut. The Invisibility Cloak is supposedly able to hide the wearer from Death himself and yet Dumbledore just looked right into their eyes like the cloak wasn't there.
I can't think how he was able to do that. Was it a spell? Or is he so awesome that he can psychically just know?
