A Smoke Alarm Triggered From the Great Beyond?

 Less than an hour ago a very strange thing happened in the house where I live. The house's state-of-the-art Google Nest smoke alarm system went off, causing smoke alarms to go off all over the house. I and another occupant of the house looked in every room, and found no trace of any smoke or mist. No one was cooking at the time. The last person to cook was myself. I had taken a few minutes to make an omelet about 25 minutes before the smoke alarm went off, but I had used the ventilator fan, and had turned off the gas. The electrically powered smoke alarms of the house are all on the ceiling, 9 feet or higher than the floor below them.  There was no electricity anomaly. 

We have the mystery of what caused the smoke alarm to go off. There was no sign of any smoke or mist in any room of the house when the alarm went off; there was no odd smell anywhere;  and all occupants are non-smokers.  The whole house was clean, and no one in the house or its yard had been doing anything this day to raise dust, or anything unusual  The Google Nest system (which gives audible messages) said the alarm came from "the den."  There is no room in the house we call a den. Conceivably someone setting up the system may have labeled one of the house's rooms as "the den." 

I have an interesting speculation that could conceivably explain the event. Maybe the event was caused by communication from the Great Beyond. My late father's name was Dean. Imagine that you are some invisible power that has the ability to make a fleeting manifestation in our world. You might choose some type of manifestation that has a  resemblance to your name. So if I died and my soul survived and I wanted to leave some manifestation indicating I had survived death, I might perhaps leave a mysterious mark on the wall.  That mark might be a sign that some manifestation had come from Mark. (The English word "mark" meaning a variety of things including "a small area having a different color from its surrounding" has the same spelling as my name Mark.)

In this case the word  "den" resembles my late father's name: Dean. How would a deceased Dean try to leave a sign? Maybe by triggering a smoke alarm in a way that would cause it  to speak a word ("den") close to the sound of his name, Dean. Of course, this hypothesis is highly speculative. 

I do know that the same smoke detector mysteriously went off (when there was no smoke or mist in the house)  on the night a relative of mine died far away, as I reported here.  See my post here for something very spooky that happened where I live on my late father's birthday.

I get many mysterious-seeming events like this where I live, such as my PlayStation machine mysteriously turning on by itself ten times on ten different days, and a green light in the bathroom mysteriously turning off and on dozens of times. 

In the nineteenth century a huge number of people reported seeing dramatic signs they interpreted as manifestations from the dead. To read about the reports, read my "Spookiest Years" series here, here, here, here, here, here, here, here, here, here, here,  here, here and here.
