[Star Wars] Why is Luke better at using the Force upside down?

In the Wampa cave on Hoth, to grab his light saber; while training on Dagobah, when he gets his vision of the future; while hanging from the antenna under Bespin, to contact Leia.

It seems that some of his greatest instances of using the Force were while upsides down. Coincidence? Explanation?

Luke started using the Force relatively late in life. As such, he had developed preconceived notions of what was normal, and what he was capable of. In order to fully unlock his Force potential, he had to lose those notions; he had to, to paraphrase Yoda, unlearn what he had learned.

Getting turned upside down is a disorienting experience. It disrupts your normal view of the world, and your place in it. When Luke was upside down, his mind was able to go to places it wasn't ordinarily, because he was so misconfabulated by his upsidedownness. It was the physical equivalent of a koan.
