Wow Gina... that is a very strange story.
The strangest thing, to me, is the fact that Lonnie was watching the microwave from the other room... "when the #5 button beeped and the auto start began running again".
That is just plain "spooky."
Can't say for certain what was causing the mysterious events in your home last night ... but, I would definitely try to pay close attention to any other anomalous occurrences, and see how they might be somehow related.
Yes, I imagine, there is always a chance that it may be a deceased relative (like Carl) trying to get in touch with you... but, until more evidence is collected and more events are witnessed, you will just have to chalk this one up in the "unknown" category for the time being.
Please keep us posted on any news, okay.
Gary
