Bump in the night

I read a post this morning from Jonathon, he was saying since his Mum died strange things have been happening. Her I pad which he only knows the Pin number to starts up on it's own after a loud bang, the kitchen light is on when he went to have a shower yet his Dad was asleep. He's not sure if he believes in Ghosts but he he thinks his Mum is still around him or playing tricks on him. Maybe his Mum is letting him know she is watching over him. This is smoke from an incense stick. Late home from work tonight two late days in a row.
