The truth was, that a superstition of his had failed, here, which he and all his comrades had always looked upon as infallible. If you buried a marble with certain necessary incantations, and left it alone a fortnight, and then opened the place with the incantation he had just used, you would find that all the marbles you had ever lost had gathered themselves together there, meantime, no matter how widely they had been separated. But now, this thing had actually and unquestionably failed. Tom's whole structure of faith was shaken to its foundations. (8.7)
Here, we see that Tom really does treat his superstitions seriously; they are, as far as he knows, laws that guide daily life.

"Say, Hucky -- do you reckon Hoss Williams hears us talking?"
Even when their fears are normal or understandable – the whole ghost in the graveyard thing is pretty standard – Tom and Huck take things to a new level; they are very serious about the supernatural.

Then a faint moan came sighing through the branches of the forest and the boys felt a fleeting breath upon their cheeks, and shuddered with the fancy that the Spirit of the Night had gone by. There was a pause. Now a weird flash turned night into day and showed every little grass-blade, separate and distinct, that grew about their feet. And it showed three white, startled faces, too. (16.57)
Here, again, Tom, Huck, and Joe, explain away a surprising natural phenomenon by turning it into a matter of spirits and spooks.
