Why do people wearing a headband with two flashlights or candles when acting crazy or out of place? So sometimes in Anime and Manga when someone is acting crazy or out of character when on a rant they wear a headband with two flashlights or lit candles pointing up.



I am wondering what the reason for this is or if it symbolizes something.
It originates from Ushi no toki mairi

Wikipedia Explanation


  Ushi no toki mairi refers to a prescribed method of laying a
  curse upon a target that is traditional to Japan, so-called because it
  is conducted during the hours of the Ox (between 1 and 3 AM). The
  practitioner—typically a scorned woman—while dressed in white
  and crowning herself with an iron ring set with three lit candles
  upright, hammers nails into a sacred tree of the Shinto shrine.
  In the modern-day common conception, the nails are driven through a
  straw effigy of the victim, impaled upon the tree behind it.
  The ritual must be repeated seven days running, after which the curse
  is believed to succeed, causing death to the target, but being
  witnessed in the act is thought to nullify the spell. The Kibune
  Shrine in Kyoto is famously associated with the ritual.
  
  The woman performing the curse is generally portrayed as dressed in white, 
  with disheveled hair,wearing an iron "crown" that holds three
  burning candles, suspending (from her neck) a mirror upon her
  chest (which lies hidden) and wearing a pair of tall
  clogs (geta), She would then nail a straw doll representing her
  target to a sacred tree (神木 shimboku) at the Shinto shrine.
  
  The iron "crown" that she wears is actually a tripod (五徳 gotoku) (or
  trivet, a stand for setting cooking pots, etc., above a heat
  source) which she wears in inverted, slipping the iron ring over
  her head and sticking candles on its three legs.


In Anime and Manga, this kind of action tells the Audience of the current genre. Usually this action in Anime/Manga is a joke (for entertainment purposes) not to mention the character you showed us wants to curse someone (except the genre of the manga/anime is a thriller or horror).
