I’ve spent about 50 years ‘checking out’ stories like this.
I’m sure there are all sorts of ghoulish things floating around in a sort of ‘astral’ realm; they’ve been created by the unwholesome convictions and imaginations of millions of people over centuries. If one’s mind is running along the same lines, one comes into contact with them.
It’s extremely important to be careful of what you believe with strong conviction, because faith is a kind of creation; and I believe that you’ll surely encounter everything that you’ve created. “According to your faith be it done to you.”
Well, although it is not the main message of the grace of Christ, Hell is real and sometimes knowing that may be important.
