Summoning stuff won't really explain it since these guys can literally summon the god of death himself..and them being summoned doesnt necessarily mean they are from a specific dimension..we've had a glance of the afterlife a few times...after kakashi died when he met sakumo...after Obito died...we saw Minato staring at the ocean (probably just his chakra) at the pein vs naruto battle and each of them differed......So a spiritual realm is a more suitable way of addressing it ;_;
