[8] Slavonic spirits and deities remained a popular element of rural Polish folklore at the turn of the 19th and 20th century, as shown by Władysław Reymont in his Nobel Prize-winning novel Chłopi (The Peasants).

Farther north and west in formerly predominantly Slavic-speaking areas of Germany, especially in the state of Brandenburg (Low Saxon Branneborg, Sorbian Braniborska), a related mythological spirit appears to be the Roggenmuhme ("lady of the rye") that makes children disappear when they search for flowers in among the tall grain plants on hot summer days.
In the vicinity of Prudnik in Upper Silesia, people believed in the Cornflower Wraith (Polish Chabernica), a demon similar to Lady Midday.
Those, who she thought deserved punishment, were put to sleep with her whisper, after which she caused them headache, paralysis or low back pain.
