 * 1) Either some "inner world" that only exists in the minds of the Dragons or the Dragon Slayers acted as a kind of portal into other dimensions in which the Dragons were hiding... at least that's the only two things I can think of right now.
 * 2) Grandeeney initiated some remote communication, so I don't see why it would matter all that much where exactly Igneel was. It wasn't like she personally flew over to him in the first place.
 * 3) Since she could establish remote communication with Igneel, it isn't hard to imagine that she could do the same with Porlyuscia. How/Why she chose Porly to become the person to give Wendy this knowledge is a different matter though, since she couldn't really have known that Wendy would visit Porlyucia, unless the communication happened while Wendy was already on her way to the tree-house.
 * 4) Maybe... or maybe a part of their parents lives on in their bodies. Or maybe it's a reaction to Igneel beginning the process that ended with his emergence.

For me it's only a plot hole if it isn't explained after the entire story is over. Right now it's just something we don't yet know. Though I guess with this interpretation of the meaning of plot hole I'm probably in the minority.
