연등 (yeon-deung) are colourful paper lanterns hung outside Buddhist temples, especially around Buddha's Birthday. Their warm glow makes them a recognisable nighttime landmark all over Korea, which is why the caller uses them as a meeting-point marker rather than a street address.
개또라이 is a crude compound of 개 (dog, used as an intensifier) and 또라이 (nutcase or lunatic). Together it means someone who went completely off the rails or acted in a genuinely unhinged way. Nari is using it as blunt self-criticism rather than an insult aimed at someone else.
The words Haetsal chants reference 천지왕 (Cheonjiwang, the King of Heaven and Earth) and 칠성님 (Chilseong, the Seven Stars deity). These are figures from Korean shamanism (무속, musok), and invoking them in a rhythmic chant is a standard way a 무당 (mudang, shaman) would call on divine power to expel a malevolent spirit.
덜미 literally means the back of the neck or nape, and in shamanistic practice it refers to seizing a spirit by this weak point to trap or subdue it. Haetsal is saying she will use herself as a spiritual anchor — letting the curse's energy latch onto her so Siwon cannot escape while Seah searches for the real red phone.
향 (hyang) is the incense burned at Buddhist temples, ancestral shrines (제사), and shamanistic rituals. In Korean supernatural belief, a persistent scent of incense on a person can signal that spirits or ritual energy cling to them. The cursed Nari noticing that Seah's incense smell is different from her own home's suggests she can now sense these spiritual traces directly.
명주실 (myeongju-sil) is white silk thread, a key material in Korean shamanistic ritual. It is used to connect, bind, or mark boundaries between the living world and the spirit world. Haetsal saying her own blood soaking the silk thread strengthens the trap is consistent with the idea that a shaman can sacrifice personal life-energy to tighten a spiritual seal.
The farewell spoken to Hyeong-uk echoes the language of a 천도재 (cheondo-jae), a Buddhist or shamanistic rite performed to help a restless soul move on peacefully. Telling the deceased to 'leave your pain here and go to a good place' (좋은 곳으로 가거라) is a very familiar phrase from these ceremonies, and Korean viewers would recognise it as a proper, loving send-off rather than just a casual goodbye.
저승차사 (Jeoseung Chasa) are the divine envoys who escort the newly dead to the underworld — roughly equivalent to the Grim Reaper in Western culture. 삼도천 (Samdo-cheon) is the three-way river that souls must cross to reach the afterlife, drawn from Buddhist cosmology long embedded in Korean folk belief. Bangul joking that he was almost across the river is a culturally vivid way of saying he nearly died.
Throughout the series Haetsal has been unable to leave a specific location — a restriction placed on shamans or spirit-workers who are bound to a space by the curse they are managing. The idea that a 무당's power can also become a cage is a recurring motif in Korean supernatural dramas, where spiritual ability always comes with a corresponding cost or confinement.
