I think the candles and ghosts connection is the thing where people light a single candle, go into the bathroom with the lights off (obviously), then stare at their face in the mirror to try to summon a ghost.
I read some very interesting articles not long ago which described the resulting phenomenon. Apparently it's a real thing. In very dim lighting, and staring fixedly at your own face in the mirror for a long time, your brain does something weird and tries to "fill in the gaps" I guess, and you see a distorted version of yourself, often something horrible.
It's similar (I think) to that slideshow thing you may have seen several years ago online that had well known celebrity faces popping up in each image, but the image was split down the middle and a different celeb was on each side.
Apparently, the viewer ends up seeing a wildly distorted mash-up of the celebrity faces. It goes back to the "missing info" phenomenon. The brain is viewing the combination of two well-known faces but as they blip by at a rapid pace, the brain tries to fill in the missing half from each person and produces a distorted result.
Anyway, that's my random tangent for the evening.
And NO I will NOT be trying the dark bathroom mirror ghost thing. Ever. My dreams are disturbing enough already.
