She's been getting worse, literally BY THE DAY, that there are people, or a person, hiding in our backyard, or near our wall, and WON'T take my answer that, NO, there's no one there (even after she's concerned me enough that I've gone out with one of my two FIREARMS) only to find that she's imagined the whole thing!!! Today, JUST TODAY, she's alerted me FOUR TIMES already!!!! What can I do? HOW can I deal with THIS? WHAT do I say to her aside from already going out to "look" for these imagined intruders (again, FOUR times just today!)??? Please help me!!!
