Changelings
According to popular superstition, the dwarfs, in envy of man’s taller stature, often tried to improve their race by winning human wives or by stealing unbaptized children, and substituting their own offspring for the human mother to nurse. These dwarf babies were known as changelings, and were recognisable by their puny and wizened forms. To recover possession of her own babe, and to rid herself of the changeling, a woman was obliged either to brew beer in egg-shells or to grease the soles of the child’s feet and hold them so near the flames that, attracted by their offspring’s distressed cries, the dwarf parents would hasten to claim their own and return the stolen child.

The troll women were said to have the power of changing themselves into Maras or nightmares, and of tormenting any one they pleased; but if the victim succeeded in stopping up the hole through which a Mara made her ingress into his room, she was entirely at his mercy, and he could even force her to wed him if he chose to do so. A wife thus obtained was sure to remain as long as the opening through which she had entered the house was closed, but if the plug were removed, either by accident or design, she immediately effected her escape and never returned.
