I once heard of a connection or explanation for some haunting being related to a houses being built upon wells or underground caverns. I tried googleing but can not find any thing. Has any one heard of this? I belivei have heard it to ways. One wass that the cavern or water could cause an effect much like emf. The other was it acted as focus for the spirits. either way I wanted to investigate the connection or explantion but cant find anything but bs on google.
