My cousin told me when they moved into their new place, the dog chose this one spot out in the backyard and woud always bark, stare at, circle around for long periods of time. Then one time one of their friends, who's all into black magic and all that shit, comes over and she starts telling them there is a bad energy in that same spot where the dog always is. So my cousin's husband start digging as much as he can in that spot and he finds.....
Nothing!
LOL he was pissed, and they still believe to this day that there is something there!
