I'm not sure what my "Official" stance is...however, my personal experience with the 'spiritual' or 'other' side of things is being alone in my in-laws house, and having just gotten out of the shower, I walked across the hall into my bedroom and began to towel off...with door open of course, cause that's how I roll... ;)
Anyway...I'm turning around and I see a man walking past the door...a tall man, black hair, short and wavy ala 40's haircut...with button down oxford shirt, khaki pants...
I screamed bluddy murder, and threw the towel around me and ran out of the room to confront the man (I'm a black belt in karate.) only...no man. He was heading towards the other end of the house, away from the stairs and the only way 'out.'
Of course I keep this to myself till my in-laws and hubby get home. I tell the mom-in-law and she pales, runs into the room and pulls out an old picture from her album. Her dead father...it was a spitting image of him when he was younger. I had NEVER seen a picture of him...I had only met him weeks before he died from lung cancer and he looked NOTHING like the young man in the photo.
Do I believe in the spiritual? Believe is a strong word. Possibility? Sure...why not. I have had 'faith' in far sillier things in my life by comparison.
