oh sorry, just remembered I posted here....
long story - I'll tell it as briefly as possible.
When I was younger, my parents had a lodger living with us - he was a family friend, not a random stranger.
Anyway, he had something wrong with his spine that needed surgery and got addicted to the codeine after the operation... he abused my mother for ages (without the family knowing, obviously) and one night, a long time into the abuse, I was downstairs with my mum when he kicked off
He kicked her into their open fireplace - fortunately not lit at the time - and threatened me aswell. Mum and I retreated into the kitchen (he was in the front room - the stairs are in the hall, to the left of the front room, the kitchen behind the hall) and when we heard him snoring, we crept upstairs
I was terrified to go to sleep and so lay stock still on my bottom bunk - my sister was on the top bunk, and I would not go to sleep incase he came and got me in the night as he'd threatened
Anyway, after a little while I heard him coming up the stairs to his bedroom (next to mine) and quickly threw up a "God, protect me" prayer
Immediately, (this sounds like a cliche, but I swear it happened) a bright figure was sitting on the end of my bed, surrounded by the most lovely shade of white/yellow light.
It (he, i think) said "don't be scared of him - he's not brave enough to come in here now" .... and he didn't - he went to his room and slept for the next day.
I honestly feel that it was an angel. What else could it be - it was as real as I am alive today; not a hallucination.
