Had one of those ball lightnings or whatever it is come into my room one time.
Didn't see it come in, saw it leave though.
It appeared as a glowing ball of gold light that had like solid black and gold ribbons coming off the back of it.
It moved really slowly through my room and after about 10 seconds of that it all sucked itself ribbons and all within like a millionth of a second into one of my light bulbs. I never saw it again.
It almost felt like it was watching me, like it was sentient, and then realized I was aware it was there.
