I always chalk it up to your spirit guides or guardian angels trying to get your attention. If they wake you up, there is a good reason. Could one of you possible have sleep apnea?

One time I had just painted my daughters room and I told her that she had to keep the door open to air it out that night so the fumes wouldn't harm her.

In the middle of the night I was awoken by my doorbell ringing over and over again. I got up and looked around and no one was there. Then I noticed my daughter had closed her door. So I reopened it again. I always believed that the doorbell was to get me to awake and take care of a potentially dangerous situation.
