Yinepu this has nothing to do with Metallica, the same would of happened if it was any other rock group. To get to you dark energies come through anyway it can, no matter what it is. I know because I have been through it. People like ourselves are on the radar more than the average Joe because we emit a certain light that they are attracted to more. Before I became who I am now, I use to astral project and didn't protect myself at all. I picked up dark energies and brought them back with me, and shortly after my clairvoyance came in strong I detected these dark energies, and it took me a little time to get rid of them. Now I walk in the light always, and I am fortunate to have my God given gifts to detect and fight these dark energies. Like I said, a lot of people don't pay attention to this, even if we walk in the light you still attract, but its very hard for them to hide from someone like myself. They can't attach themselves to you if you are protected but they can in fact send you negative thoughts, this is where thinking happy thoughts all the time comes in, you develop a way to block those psychic attacks. They will try to freak you out anyway then can Yinepu, don't ever underestimate dark energies. I speak from experience.
