Ghost, entity, psychic energy from pubescent girl living in the house, demonic presence, or sleepwalking?

Ok, ok, ok: If you read this, I want your opinion because I am really freaked.

Last night at 2:35am I was woken up by a noise (I think), I sat up partway waiting to hear more. I was not at all scared, just curious. I did not hear anything further but saw a column of pale blue movement in my left periphery. I looked directly at it and saw nothing. I went back to sleep again after getting up for a pee and leaving the light in the ensuite "on" on purpose. The pale blue thing kind of scared me so I thought leaving a light on couldn't hurt.

When I got up in the morning after my alarm went off and reached for my robe which is always at the foot of my bed, I found that instead of being there, it was splayed out on the other side of the bed. It wasn't crumpled up at all it was laid out neatly: the shoulders were where someone's shoulders would be and the arms were where someone's arms would be if they were lying in bed beside me. It was as if someone put it there very carefully.



There have been unexplainable things in this house before but never quite so freaky, they were always things I could explain away. Such as: sounds of people talking where there are none, footfalls in the hallway where no one was walking, once a flower flew out of a vase about 5ft vertically and tapped my son on the tummy, (that was impossible to explain away, actually) and a number of times the lid on the garbage can moved by itself.

What do you think?
