Let me first start by saying that I am a very rational person. This is not a story I tell everyday.
I am of cambodian decent. My uncle is a... "shaman". I don't know the right word for that but, he chases and talks to ghost. It wasn't his job since he cannot make profit from it (long story). But I assisted one of his things.
Basically, he took an egg, melted some wax on the big side of the egg, and glued small candle on it.
He then proceeded to put the small side of the egg on the ground... told something in sanskrit, and released it. The egg was holding still, standing, with a candle on its head burning.
He proceeded to ask his questions, it was about a relative that just died. I didn't very listen as I was looking at the egg. As soon as he finished, he said "as soon as the candle is finished, the spirit will go away. in the meantime, don't touch it".
So I stayed there with my brother, looked at it. As soon as the candle finished, the egg rolled down.
I was 12 years old at the time. I still can't understand it. It's not something I tell people everyday by fear that they will think I am a fool.
tl;dnr: Ghost story with a egg standing upside down.
