I've mentioned this before, but currently it's both unconfirmed and untested.
Rather than just stating that thigns that people hear or see is just optical tricks of the mind from shadows (one of the simplest reasonings for such phenomona).
I suggest that what you actually see is the universal alterations caused by a parallel universe. basically for my suggestion to be accurate a physicist could generate a paradox in a laboratory and that initial experimentation can set off a Butterfly Effect of of cause and effect.
(For instance in one universe they go home 5 minutes earlier than the other, which means they get stuck in traffic in one and not the other, which in turn causes people in the traffic queue to be displaced with the location they would be, which in turn means one person doesn't make some traffic lights which means they get caught by a bridge going up and inturn they don't make it to the sale of a house for 30 extra minutes, but that time the couple have lost interest and don't want to buy that specific house and someone else ends up buying it and moving in. )
This means that in this universe, you and your wife are in that house, however in another universe it might be another family all together. You should find that the more differences you generate between your universe and their universe will lower the amount of occurances you notice (This is where entropy comes in, for instance you might have the same lightbulbs that came with the property in your lighting, changing the bulb generates a "universal" change between the two universes and therefore a duality of shadow cast from the initial bulbs light would possibly stop. In fact you don't even need to buy new bulbs, just rotating them slightly or mixing them up could fix the shadow problem)
As for the doorbell, if it came with the house you could change the cable for it, or even change the doorbell all together, this will make it incompatible with the super-positioned subatomics of a parallel universe.
Just remember that you see ghostly shapes in this universe and those "on the other side" (in another universe) are potentially seeing you and your family as ghostly shapes. Since you knocked down a partition wall, you can now creep them out by walking through a wall
[I have actually shared my house with a bunch of parapsychologists in a parallel universe, I spotted them one day taking a picture with a camera in the mirror, as if they were standing where my reflection was.]
