Hingedeajal ...
austati ja oodati koju surnud esivanemate hingi
käidi marti jooksmas
riietuti hirmuäratavalt, et vaime eemale peletada
Miks tulevad eestlaste uskumustes hinged koju?
nad tahavad koju kummitama jääda
nad tahavad pereliikmeid hirmutada
nad tahavad näha, kuidas nende töid ja tegemisi on jätkatud
Mida tegid vanad eestlased sügisõhtutel reheahju ääres?
küpsetasid leiba ja grillisid
pajatasid erinevaid lugusid ja meenutasid minevikku
ennustasid ja nõidusid
Mis oli surm vanade eestlaste arvates?
elu loomulik osa, mida ei ole vaja karta
karistus elus tehtud vigade eest
raskest elust pääsemine
Mida pandi inimestele hauda kaasa?
süüa ja juua
relvi, ehteid ja raha
tööriistu ja riideid
Kuidas võeti hingedepäeval hingi vastu?
köeti saun ja kaeti laud
mindi kodust ära, et hinged saaksid rahus olla
korraldati suur ja uhke pidu
Miks pandi lahkunutele hauda esemeid kaasa?
hing võib muidu vihastada ja kätte maksma tulla
perel endal ei olnud neid asju enam vaja
sest hing jätkab elamist mujal ja saab neid asju surmajärgses elus kasutada
Mida tähendab väljend "õhk on hingekesi täis"?
sel aastaajal on ilm sompus ja udune
hingedeajal on väga palju hingi ringi liikumas näha
sel ajal juhtub palju ebaloomulikku ja seletamatut
Mis oli hingedeajal keelatud?
(vastuseid võib olla mitu)
naljatamine, naermine
müra tegemine, kisamine
kärarikkad tööd
(puude lõhkumine)
villa ja lõngaga seotud tööd
Kuidas tähistatakse hingedepäeva tänapäeval?
(vastuseid võib olla mitu)
käiakse surnuaias
lastakse ilutulestikku
süüdatakse aknal küünal
Hingedeaeg on midagi väga ...
õudset ja hirmutavat
püha ja erilist
Mida tehakse Lääne-Euroopas ja Ameerikas halloween'i tähistamise ajal?
püütakse hingi ära peletada, sest usutakse, et nad on kurjad
oodatakse samuti hingi koju
