Well, this does seem to be connected to her somehow. We can't say for sure since we aren't there with you, but there is such a thing as poltergeist energy that can happen. Really not sure on this one if there is no other activity.My spouse was away for 8 nites, while my doorbell did not ring during that time, the nite before my spouse returned the doorbell ranf at EXACTLY 7:57 at our son's home where my spouse was visiting. No one was at the door.
