If you believe everything the saints and orthodox church says, then you should believe this also:
St. Mark of Ephesus:
"But if souls have departed this life in faith and love, while nevertheless carrying away with themselves certain faults, whether small ones over which they have not repented at all, or great ones for which – even thought they have repented over them – they did not undertake to show fruits of repentance: such souls, we believe, must be cleansed from this kind of sin, but not by means of some purgatorial fire or a definite punishment in some place (for this, as we have said, has not been handed down to us). But some must be cleansed in they very departure from the body, thanks only to fear, as St. Gregory the Dialogist literally shows; while others must be cleansed after the departure from the body, either while remaining in the same earthly place, before they come to worship God and are honored with the lot of the blessed, or – if their sins were more serious and bind them, for a longer duration – they are kept in hell [i.e., Hades], but not in order to remain forever in fire and torment, but as it were in prison and confinement under guard" (First Homily: Refutation of the Latin Chapters concerning Purgatorial Fire, by St. Mark of Ephesus. Qtd. In "The Soul After Death, p 208f).
Which means hell is not eternal or they possess earthly house as ghosts according to the above person.
