Debunking a Frightening Alarm

The most important thing when dealing with ghosts and spirits is making sure that they're ACTUALLY communicating with you. This week I had to do some debunking.
We had recently installed a new digital alarm clock in our guest room (the floor over our bedroom). It was plugged in around 11:41 a.m. and we set the proper time on it.
We didn't read the directions (yes, I know I should have!) and didn't note the 4 settings on it, one of which was "alarm off." On this clock, if you leave the setting on "set time" the alarm automatically goes off at "12 a.m." (after about 15 minutes it stops itself). Well, last Sunday and Monday we were so tired we slept through the alarm going off at 11:41 p.m. (which is 12 hours from the time we originally set it).
Last Tuesday, however, I was awakened by it, and ran upstairs wondering if a ghost followed me home and was playing with things in the house. I immediately unplugged it and didn't sense anything.
It was plugged back in the next morning (and we overlooked the alarm off switch again). Of course, it rang again while we were sleeping and startled me! So I ran upstairs and unplugged it... wondering again if there was an entity in the house playing with the electricity. I picked it up and looked closely at the alarm and that's when I saw the "alarm off" setting. DOH!
So, this was a good experience in debunking communications from the other side. It could be a ghost, or it could be your own stupidity with alarms, as it was in my case!
