It wont happen in this world, Hell, Hades, Gehenna, Lake of Fire are all someplace where wicked people go eternally separated from God.
Jesus sends them to a final destination after they are judged by their works - deeds.
Not an illusion, it happens, Christ is Lord of the living and the dead. All people.
Romans 12
9 For to this end Christ died [b]and rose and lived again, that He might be Lord of both the dead and the living. 10 But why do you judge your brother? Or why do you show contempt for your brother? For we shall all stand before the judgment seat of [c]Christ. 11 For it is written:
“As I live, says the Lord,
Every knee shall bow to Me,
And every tongue shall confess to God.”
12 So then each of us shall give account of himself to God. 13 Therefore let us not judge one another [d]anymore, but rather resolve this, not to put a stumbling block or a cause to fall in our brother’s way.
Romans 3:20
Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin.
Romans 3:28
Therefore we conclude that a man is justified by faith apart from the deeds of the law.
Romans 3
30 since there is one God who will justify the circumcised by faith and the uncircumcised through faith.
Romans 4:7
6 just as David also describes the blessedness of the man to whom God imputes righteousness apart from works:
7 “Blessed are those whose lawless deeds are forgiven,
And whose sins are covered;
8 Blessed is the man to whom the Lord shall not impute sin.”
2 Corinthians 5:10
For we must all appear before the judgment seat of Christ, that each one may receive the things done in the body, according to what he has done, whether good or bad.
Well, imagine being judged to see if you are worthy for eternal life by your works!
