Well, he [i]did[/i] wake up while falling through the air. Perhaps he hallucinated it while making his way back to his Bonnie and Eralion? Tini probably isn't very good at being alone, so I think it'd make sense if he created friends in his mind.

Edit:
Yeah, I can definitely see Tini as the type of person to leap through a cave or wherever fighting off imaginary monsters.
