Omg something similar like that happened to me. A few years ago in December I was at my old mental health clinic waiting for my mom to pick me up. I then had a random thought of “what stops someone from going into a metal health facility like this and start opening fire?” Then when I was at home they had a breaking news announcement that there was a shooting in a mental health facility in California. It had literally been starting to happen right when I was having those thoughts.
