well obviously. everything in the actual show. was re-done because obviously supernatural events wont happen twice. but they say on the show that all the things really did happen. i mean i guess it just comes down to if you believe it yourself. i mean some of the things, such as the crabs coming out of the dudes chest, are hard to believe. but like the kid that saw the dead guys spirit, i believe that one. idk. i guess it just comes down to what you think.
i personally think that everything that happens in it is real, despite some are hard to believe.
