My Wife Says She Is Haunted By Ghosts

My wife has maintained throughout our relationship that she has been haunted by a ghost. I tend to be skeptical of this, but would like someone else's opinion of this. My first experience with it was several years ago.

We had both fallen asleep, but several hours later I woke up to find the bedroom light on. I remember turning the light off before falling asleep. I stayed there for a minute thinking that I was confused and we had fallen asleep with the light on, when I hear our oven turn on in the kitchen. I should mention here we were living in a small apartment with the bedroom next to the kitchen. The sound of the knob clicking into place on our oven got me out of bed. I come out to the kitchen to find the oven heating up, and the lights on in the kitchen as well. My wife slept through the whole event.

The second experience occured last summer. I had been deployed to Iraq and was home on R&R. We had locked up the house and gone to bed. I know everything was cleaned and put away before we went to bed because I saw to it myself. In the morning when we went into the kitchen for breakfast we find every cupboard door opened. Not opened like someone was looking through them. Each door was opened perpendicular to the wall.

I've seen war, but this event here scares me more than getting shelled. I think it is because there still is no explanation for what happened. I still maintain that there is a reasonable explanation for what happened, but I would like to gather someone else's opinion. My wife has told me of other events that have happened to her before we met, but because I wasn't there I can't verify the truth of the story.

So any ideas?
