Hi Ehrin;
I had a very similar thing happen to us on a jobsite, where we were
renovating a home. Turns out the previous owner had put a nail
through the power line leading to the light, which shorted the neutral
to hot, which started blowing up the light bulbs, and making even the
casing of the light 'hot'. Could've burned the house down. We
started tracing the lines, and eventually found the nail through the
electrical line.
You should look at where recent screws or nails have been added,
likely a line has been compromised, or there is a short inside the
electrical box up top. Could even be a roof leak shorting out that
box....
