Before you write yourself off as a nutjob -- I'm trying to remember the book I read years ago by Billie Grahams wife that told how a spirit came to her one night and woke her from a sound sleep. It's been years since I read it and can't remember the whole story now, but it's not unusual for apparitions to come to us when we're in a relaxed state and they don't have to speak to portray a message to us. We have to be open. I used to be much more open before I got so intense over politics.
I don't really think I'm a nutjob. Well, at least not by reason of those 'apparition' perceptions. In my opinion, they were the result of the heavy mental, emotional, and physical duress I was under at those times (with the exception of the last set of occurrences, which I think were due to the architecture of that house before the additions). The first two in particular were just so remarkably vivid they made a definite impression to say the least. If there was a message involved, it was probably: "Get the heck out!" ;^)
