Rather in a dream or real life...this person has fulfilled his purpose while in the land of the living and is deceased. First) All go unto one place; all are of the dust, and all turn to dust again. Ecclesiastes 3:20.....Second) Ecclesiastes 9:4-6 For the living know that they shall die; but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten. 6 Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun... So we now know that the devil want us to worship the dead which is definitely against the will of God. This is also called "Necromancy" meaning dealing with the dead. It is NOT of God! God would not bring back a deceased love one and put them before our face. Neither does he give us the spirit of torment. Torment is fear!
