Dwelly doesn’t have foragradh, but faragradh is defined as “weltering; foundering; bathing; report”.
DASG has plenty of entries for faragradh too, many of them featuring in the Cape Breton periodical Mac-Talla. Often the faragradh is not the spooky thing itself but a reaction to it. Quite by chance, this one describes the print I made to illustrate the feadarraich:
“Calum understood that Donald saw or heard something distressing that caused him faragradh, and he looked keenly at everything before him. He noticed too animal eyes shining in the firelight like two stars.”
The same periodical also uses faragradh for the spooky noise itself: “..he thought he heard some sort of movement or faragradh in a remote part of the cave.”
