When working with many mentally challanged individuals i would notice a higher amount of paranormal activity occuring in their homes. In one of the homes several staff and myself noticed a very unusual occurance. The home had 3 men living there, one of them being schizophrenic. He would be fine until he went in his room then he would scream "no the boy is good, the boy is going to hell. They are coming to take the boy to hell." The staff would check on him and he would always be staring off into a certain corner of the room. After several weeks of this activity begining the staff started noticing that bugs would begin to move to this corner and die. The strange part was that it was many typesfrom spiders to ladybugs and not just a few but hundreds daily. Every morning after he left for his day program staff would clean up the grouping of dead  bugs and by the next morning the formation of dead bugs were back in this corner. This occurred every day until he passed  away. My question is if anyone has heard of something like this before and what could it be?
