Strange Falls, Spontaneous Combustion and Other Odd Events

What is a meteor or meteorite?
A meteor is a small body of matter apparently from outer space that upon entering the Earth’s atmosphere resembles a streak of light, what we normally call falling stars.
A meteorite is one of these that successfully hits the ground!
Until 1803 most scientists regarded falls of meteorites as absurd and fantastical. As well as impossible. This was until the massive fall onto L’Aigle in France of thousands of meteorites on April 23rd 1803. Previously on November 11th 1799 there had also been a massive meteor shower comprising thousands of meteors that was seen all over the Earth. This is now known to be the Leonid Meteors whose falls have diminished since. The Leonids come around every November, usually near the beginning of the month. Funny how this is a peak period for UFO sightings!
That was accepted meteorites.
Then you have such things as Black Comets. Black comets are extinct cometery nuclei which no longer create outgassing. No tail is visible. They are black and difficult to see in space unless they are passing celestial bodies. Even these seem apparently normal when you look at everything that has come crashing down, sometimes heavily and sometimes lightly, from the skies.
Amongst the true meteorites and possible fragment of black comets, and possibly even antimatter, and even large blocks of ice, what then are the rest of these?
What are events of spontaneous combustion?
What are falls of non-meteoric stone?
What are all of these bizarre non-classifiable events from falling animals, that normally are not airborne to terrestrial stones crashing down from the heavens.
Read on and be amazed.
