my frenz it is simple... remember elise warning before he go to the further that he must act like he among them mean he already died if they found out he not died they will chase his body.... when he on the way to his body that old lady make a trap that make he cannt return to his body...

and we can conclude what will happen when his mother show him the picture when he is boys the picture every time he snap picture that ghost even near that ghost will take his body when next time he gone travel to the further....

that all my opinion if u accept it.. for ur info i juz see that movie in midnite last nite... very good movie to watch...
