At the 2015 Greater New England UFO Conference held in Leominster in Massachusetts, this topic was discussed. One of the speakers, paranormal researcher William Hall, told attendees, "It used to be that the UFO people didn't talk to the ghost people because they were a little weird, and nobody would talk to the Bigfoot people because they were crazy. I found out, we cannot continue to do that. In reality, quantum physics is leading us there.”
