Can a Christian believer partake in astroprojection stuff?

my friend has crystals she wears around her neck and stuff and she can do astroprojection and some magnetic things(meaning she can cause lights to turn on or off and make things move ect. like magnetic ppl look it up) and she can do those things with her friends that do it...she believes in God and goes to church and things but her life is mixed up...she is realizing she can do them and she doenst know if its right or wrong...she had a vision that she was at hom and on the couch and she saw her sister and friends and they were beating the window at her and their faces disapeared then she transported to her old church and she saw ppl at church that she didnt recognize...their faces disappeared too. she then saw Jesus and he took her to a heaven like place and she was able to see the ppl finally and Jesus watched over them all. she thinks she is being told she is afraid of losing important ppl to her...idk...i am a Christian believer and i dont think this is cool stuff...she said "i can do it...if its wrong then how can i do it?" can anyone give me/us any advice? if you can give scripture to help us understand this all and why its wrong and help her see...i cant well enough explain it...like i tried to explain that i can see auras but not intentionally. one day i noticed something glowing and i researched and found i can see auras and i think its cool looking to see them but i know that stuff is demonic and i choose to stay away from it and not "try" to see it purposely. what is any advic for her on this? pray? find out why she sees this and how to overcome it? idk. thanks.
