Can ask Yahweh to remove the blinders from their minds and let them see the wonderful news of Christ.
. "...for their minds have been blinded by the god of this age, leaving them in unbelief. Their blindness keeps them from seeing the dayspring light of the wonderful news of the glory of Jesus Christ, who is the divine image of God." II Cor 4:4
Seems that the lines of communication are there between you. They'll need to be maintained. Have the life they really want - being a follower of Jesus having His peace (Joh 14:27) and love. Not an expert on this but from reading an aspect of the occult is a desire for the supernatural outside or separate from God. It's my understanding that aerial projection is dangerous which is part of the draw. But the enemy will began to demand more than what they'll want to give. They may turn to you for help. So you'll want to be prepared.
The occult seems to teach their members about the supernatural while believers in general try to avoid the supernatural or chalk up everything as ungodly. It's not unusual for there to be a mixture because some in the occult know Scripture and will use it to accomplish their goals. They may point out the following to justify aerial projection. "And when they were come up out of the water, the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing. But Philip was found at Azotus: and passing through he preached in all the cities, till he came to Caesarea." Acts 8:39-40 Or "I know a man in Christ who fourteen years ago—whether in the body or out of the body I do not know, God knows—was caught up to the third heaven" II Cor 12:2
Since God was the source of those supernatural events, they"re not dangerous for them; otherwise, they are. He'll not demand, control nor manipulate them. God loves them.
