Anyone had any unexplained things happen to them, things moving of there own acord etc? Often connected to when someone close to you has died?

At the weekend the gf was at her flat in bed on the computer and put it next to the bed so she could use it in the morning.
That night she had a dream about her step-father who died 5 years ago and in it she was having a conversation with him about how she might have still been able to speak with him or sense him but apart from a couple of things happening near te time he died there's been nothing.
Then she woke up and said her mouth was incredibly dry (and it wasn't particulary hot in the room or anything).
She went back to sleep and the next morning she walked into the lougne and her computer was on the table there. She says there's no way she would've moved it in the night and was genuinly shocked when she saw it there.

So any other similar stories? I've heard from several people similar things like that happening and not necessarily people who normally believe in ghosts and things.
