Holy crap, I ain't doing that then.

Well just thought since it's the metal of so many demons it might be a good idea to use in trying to communicate to those particular ones.

I've also had some strange sensations similar to this. It was odd. When I would be falling asleep I would sometimes experience what felt like a hammer striking the top of my head from the inside. It felt very physical and I would feel it reverberating for a few moments and faintly hear it...

I don't know if it'd be safe or not. I've heard from many people that that it is very bad for your health and from about just as many that it takes a tremendous amount of contact with mercury for it to have any ill effects upon you.
