When Iwas a teenager one of my friends had this ring that had alot of skulls on it. We always had really bad darkish feelings about it. Once on a dare I put it on my left ring finger. I didnt feel any cuts, pinches, scrapes or anything else like that, it fit really well. Took it off also without incident. But 15 ish minutes after taking it off I noticed my finger was covered in dried blood. Should I have been worried about this?
