Explain to me how this is a delusion.there are people who will stand in locations i usually travel to they wait for me as soon as they see me they pick up their cell phone dial it and look over at me and then walk away and look back a few times at me watching where I am heading to.they are always different people but they stand in the same locations.once they know a place I commonly go to they appear there as well.they all do the same thing they try to act like they arent up to something suspicious but the way they act is a dead give away.
