They have a hunch that the reason some people see ghosts is not necessarily because a place is haunted. It may be because a haunted house has a lot of mold, and breathing it alters people’s states of mind.
Shane Rogers, an associate professor of environmental engineering at Clarkson, is into paranormal activity and ghosts in general. As a scientist, he studies some icky things, like manure and mold. He put his interest together and developed a hypothesis. Maybe people who see ghosts are actually just breathing in toxic mold? “There are reports of people who have been exposed to mold who have reported things like anxiety and depression.”
Rogers also knows many alleged haunted houses are old and dilapidated and more likely to be infested with mold. He said, “If you’re in a place where you’re exposed to mold, and you’re feeling a little anxious, and you see something strange or you feel something strange, if you’re in an old house that’s a little scarier, you might be more likely to ascribe it to a haunting, whereas in a newer house, perhaps not.” Read more
