They can mean many things in many different cultures and cults, there's isn't just only one way they're seen. It all depends on each person's beliefs...
Ever thought that the person the candles fell on was messing around and accidentally knocked them down, or you'd like to describe in more detail?
No this is a person that doesn't 'believe'. He doesn't take those sorts of things seriously, and even he said it was weird. He was sort of complaining that they'd fallen on him, and I knew that they wouldn't have unless seriously knocked about. (I always drip some of the candle's hot wax into the bottoms of their holders, before smooshing them down - to make sure they won't fall when lit). Additionally, I've lived with my candelabras for about 5 years in this house -- and nothing strange has ever happened like that, individually... much less five total candle happenings in one day.
It's been happening amidst other odd things in my home... but seemed the most symbolic. I just wasn't sure what symbolism it might hold.
Thanks for the reply!
