[Star Wars] When Vader struck down Obi Wan and he disappeared, what did he think happened to his body?

He was probably confused as hell. But being the stoic killer he is he didn't show it because it would imply he wasn't the all knowing monster his men and enemies see him as. 

Perhaps he never fully understood what happened that day, the Sith do not have any such abilities and even Palpatine likely wasn't aware of such power existing.
