The waking inhuman screams of demons as I walked through a red landscape that looked like Mars, only with humanoid figures with horns halfway merged into the rocks and floor, as I felt tugged to enter a hidden cavern (but quickly left once I remembered I was asleep). It was rather unnerving.
If you knew your neighbor nearby is hoarding a lot of rifles and guns in his home (say, like a hundred or more), and you know he or she isn't exactly a calm person, would you be willing to tell the police about it?
