Episode notes
Alp-Luachra Eats From Inside While You Sleep
- Robert Lamb recounts the Alp-Luachra as an invisible creature that crawls down a sleeper's throat and eats their stomach contents.
- Hyde's tale says sleeping by a stream invites the creature, which then consumes swallowed food until the victim wastes away.
Use Salt Beef And A Stream To Lure It Out
- To force the Alp-Luachra out, Robert Lamb relates Hyde's remedy: eat lots of salt beef and lie with your mouth open over a stream.
- The thirsty creature reportedly ejects itself to drink, providing a folkloric cure in the tale.
Variants Include Serpents Hatching In Stomach
- Robert Lamb notes variant tales where the invisible joint eater sits beside the victim or where serpent eggs in stream water hatch in the stomach.
- One 1891 review says these stomach-serpents can be removed by fasting and opening your mouth to a bowl of milk.
