Here's a collection of very nice articles about some of the possible (natural) sources of phenomena perceived as "paranormal".
Ghosts in the Mind
Note that I am not saying that ALL of them - or even the majority - are, in fact, "in the mind".
But I definitely think it's useful to examine and rule out (if possible) every possible natural causes first.
P.S. It is possible that some of these links have been posted here in the past. But with such a huge amount of material I am sure nobody will hold it
against me if I (re)post them.
