Recently went to Fernald State School to do some urban exploring in Waltham Massachusetts. Caught a woman on footage telling me "get out of here" in the most modest tone. We were in this basement in this building for less than 2 minutes. Started filming outside and went in filming. At exactly 3 minute mark she walks I'm front of me you hear "womp" "get out of here" "womp" as she passes by. I click pause and there is an orb on the screen outlining here body. I honestly always was on the fence about a spirt realm. Not anymore. Its crazy.
