Ja, stenen fungerar, inte som tillverkaren / användaren skulle vilja.
Citat från DH:
Meanwhile, the second brother journeyed to his own home, where he lived alone. Here he took out the stone that had the power to recall the dead, and turned it thrice in his hand. To his amazement and his delight, the figure of the girl he had once hoped to marry, before her untimely death, appeared at once before him.
Yet she was sad and cold, separated from him as by a veil. Though she had returned to the mortal world, she did not truly belong there and suffered. Finally the second brother, driven mad with hopeless longing, killed himself so as truly to join her.
And so Death took the second brother for his own. - Harry Potter and the Deathly Hallows, Chapter Twenty-One
Det verkar i denna text att en kropp och själ återfår, men det finns en begränsad interaktion där användaren av stenen kan ha med personen. Även den en gång döda personen vill återvända till livet efter att det är där de hör hemma och är lyckligast.
