There are different kinds of SP,
I have had a really really bad experience with this and I'm not talking about it on here.
Mainly because if someone hasn't experienced it, then it can't be proved, its too subjective.
And then the conversation moves to all kinds of nonsense, and our carnal nature loves speculation.
So I'm leaving it alone, all I can say about it is, It will probably never happen to anyone on here.
If you are ministering to someone who has been through such an experience, there are some books.
The best is probably Alien Intrusion, put out by Creation Ministries.
(I didn't see any aliens but I think the experience is the same)

As an aside, my pragmatic non practicing Irish Catholic father told me before he died,
(quite by surprise) that he also had experienced this at our old house in Sydney.
and he was definitely a man of few words, also having been a Sergeant in the army,
and someone who was not given to superstition...
