Castiel's dramatic entrance causes the lights to go haywire.

Electromagnetic Interference is an ability, or a side effect of a supernatural entity's presence that causes nearby electronics to malfunction.

Species with this ability[]

  • Archangels - Raphael's arrival caused a blackout across the entire Eastern Seaboard, while Lucifer caused the lights to flicker with his mere presence at the Elysian Fields Hotel.
  • Angels - Angels' true forms counteract electronics. When Angels first appear in vessels, or sometimes when they're near electronic equipment, they can cause lights to flicker, spark, or explode.
  • Banshee - A Banshee's presence will cause lights to flicker, similar to ghosts.
  • Demons - Demons, like spirits, often disrupt nearby electronics with their presence. Large numbers of demons can cause thunder storms.
  • Ghosts - All ghosts disrupt nearby electronics with their presence.
  • Shtriga - When a shtriga entered Michael's room, its presence caused interference in the camera feed Sam and Dean were watching.
  • Reapers - The appearance of a Reaper can cause lights in a room to flicker or go out. A Reaper was also able to cause a car to lose power and stop.
  • Soul Eaters - A Soul Eater's presence will cause light to flickers, similar to ghosts and banshees
