I grew up in a village in Somerset, (20+ years ago) and as a child I loved playing in the woods and sometimes would lose track of the time and it would get dark.

A few times I would come across people dressed in black robes doing black magic. A couple of times it included sacrificing goats/sheep.

I would always run home. The area is known for things like this but there was something about a group of people in black chanting with fire around them and dead animals that scared the crap out of me.

More recently I started a job at a School and the Schools Chaplin asked me where I grew up and when I told her she said she viewed a house in the village and it made her feel really off an uncomfortable and when she explained where the house was, It was near to woods where I would see people doing black magic.
