The best thing TAPS taught us was to be a skeptic.Try to disprove.When I started ghost hunting I made sure to think like this.Two things I never believed in was orbs and the spirit box.Let's start today with orbs.To me I always thought it was just a camera/light error.They even teach us about camera shake and glare.Light off of rain, ect.In a farm house in Gettysburg my belief changed completely.We were in the attic using the spirit box."They,Or whatever it is, told us to go down stairs.They were coming.Long story short the responses indicated the army was coming.But I personally started communicating with someone or something through the spirit box.Thought I saw movement down stairs.I asked "Are you down stairs."Got a positive result.Went back and forth talking.I sensed whatever it was was by the door.I said "I see you.You're by the door."Next thing I know it was basically startled.I saw an oranges orb,2 to 3 times bigger than a bowling ball go from top of the door and shoot across over to the next  room.So while I had not believed before seeing it with my own eyes is really hard to dismiss.
