“An interesting experience is to visit Hob Hurst’s House, the Bronze Age tumulus up on Beeley Moor, especially at dusk. This ancient tomb is said to hold supernatural powers and if you listen carefully you may hear the voices of the original inhabitants.”
quoted from “The Derbyshire Village Book” 1991, according to the 2000 Derbyshire Stones Meet report at

Sounds just what you want to do – go somewhere dark and lonely and listen to your ancestors whispering away. Not terrifying in the least.
