So aboard the Falcon we've seen old Ben give Luke a lesson in deflecting blaster fire with a Lightsaber. In TESB Luke is capable of attracting objects out of reach, namely his Lightsaber in the Wampa's lair, using the Force. Though I've seen the Saga countless times, only now have I started to wonder about this: - Did Luke receive further training from Obi Wan's spirit? - Could Luke have returned to the old hermit's hut on Tatooine and retrieve something that'd aid his understanding of these new abilities? - Or is Luke just a natural and figured these useful powers out by himself?
