I don't feel beholden to follow the real world at all. The important thing is to know WHY things turned out the way they did. You need to understand the reasons for events, or at least be able to make reasonable guesses about them.
Don't get me wrong, magic is cool. But a nervous mother singing to her child at night while something moves quietly through the dark outside her house? That's a story. Handled properly, it's more dramatic than any apocalypse or goblin army could ever be.
However, while being able to think about two things at the same time is a terribly convenient, the training it takes to get there is frustrating at best, and at other times rather disturbing. I remember one time I looked for the stone for almost an hour before I consented to ask the other half of me where I'd hidden it, only to find I hadn't hidden the stone at all. I had merely been waiting to see how long I would look before giving up. Have you ever been annoyed and amused with yourself at the same time? It's an interesting feeling, to say the very least.
