Do you have a ghostly spirit?

We seem to have a spirit living in our house. I think it must be a friendly one. Nothing scary happening. It is a sneaky one that comes out at night and leaves us clues to let us know it lives with us.

Several times we've been woken up in the middle of the night to the sound of the timer going off on the oven. A loud buzzing noise that only comes on after you've turned the timer knob. So it must be one that likes to bake or perhaps just likes to see us jump out of bed. I know it's not that we have left the timer on because it could be several days after I had used the oven to bake and you can only set it for an hour at the most. It may go off at 2am and continues to buzzzzzzz until I get out of bed and turn it off.

Lately I've gotten up to the little lamp in the corner by my laptop turned on. Again, I had not used this lamp the night before yet there it is brightly shining for us to see that this spirit has been browsing through all the notes I leave scattered on my desk.

I suppose this is why our dog could be so crazy. Popping his head up from time to time glaring into the room like something is there moving about and Jim and I look around to see what he's so jumpy about and we see nothing or barking into thin air at sounds we do not hear.

I'm now wondering if this spirit has a bad sense of humor tinkering with our appliances and electronics. We've had to call repairmen several times over the last few months. We've had to repair the refrigerator, the oven and now our large screen TV will not work. We simply got up one morning last week and the TV would not turn on. It has a little red blinking light and that is all. We now have an appointment with the repairman to come out here on Tuesday.
I'm beginning to get a little annoyed with this spirit. It obviously has no clue how expensive these things are to repair!

I'd also like to know where it has hidden all the things that I cannot find. You know how you just know you've put something somewhere and when you look there it is no where to be found.

Do you have a spirit in your house? If so do you communicate with it? I'd like to know how so that I can ask it to please stop breaking expensive items, waking us up in the middle of the night and stop annoying our dog!
