When all this was happening I just gotta ask , were your lights flicking super bright then back to regular ? ( at the same time say other things getting like a tic /flick like tv screen a bit of static or same with a computer monitor) Im asking because if by chance your homes ground wire connection has failed or become loose or is broken somewhere and the wires which come to your home have had a failed connection either at the point they say connect at the pole or where the drop to your house connects to the the rest of the elect co equipment See if you have a older home with older drop and the transformer your connected to has not had to be changed or had any thing to disturb the connections to it from transformer to your home in a very very long time and the connections became damaged due to corrosion its possible that a 220 volt circuit can be created if your homes ground itself is not in good condition in order to act like a back up of sorts. ( I had a property that had been re wired in the later1950s and had just that sort of thing happen, my ground at the meter failed and just under the overhang where my drop tied to the neutral had been rained on , snowed on etc and was corroded enough to create 220 in circuits that were intended to be only 110 ( the electric utility fixed the outside connection free and I installed new grounding clamp and problem was done with)
