Nice interesting Post. It all helps the cause. ''Extreme Ball Lightning: New Physics,

''Curious Phenomenon In Venezuela
Cowgill, Warner; Scientific American, 55:389, December 18, 1886
During the night of the 24th of October last, which was rainy and tempestuous, a family of nine
persons, sleeping in a hut a few leagues from Maracaibo, were awakened by a loud humming noise and
a vivid, dazzling light, which brilliantly illuminated the interior of the house. The occupants, completely
terror stricken, and believing, as they relate, that the end of the world had come, threw themselves on
their knees and commenced to pray, but their devotions were almost immediately interrupted by violent
vomitings, and extensive swellings commenced to appear in the upper part of their bodies, this being
particularly noticeable about the face and lips. It is to be noted that the brilliant light was not accompanied
by a sensation of heat, although there was a smoky appearance and a peculiar smell.
The next morning the swellings had subsided, leaving upon the face and body large black blotches. No
special pain was felt until the ninth day, when the skin peeled off, and these blotches were transformed
into virulent raw sores. The hairs of the head fell off upon the side which happened to be underneath
when the phenomenon occurred, the same side of the body being, in all nine cases, the more seriously
injured.
The remarkable part of the occurrence is that the house was uninjured, all doors and windows being
closed at the time. No trace of lightning could afterward be observed in any part of the building, and all
the sufferers unite in saying that there was no detonation, but only the loud humming already mentioned.
Another curious attendant circumstance is that the trees around the house showed no signs of injury
until the ninth day, when they suddenly withered, almost simultaneously with the development of the
sores upon the bodies of the occupants of the house. This is perhaps a mere coincidence, but it is
remarkable that the same susceptibility to electrical effects, with the same lapse of time, should be
observed in both animal and vegetable organisms.
I have visited the sufferers, who are now in one of the hospitals of this city; and although their
appearance is truly horrible, yet it is hoped that in no case will the injuries prove fatal.<End of Sci. Amer.

Certainly some aspects of this Paper that are worth looking at in more detail.
