Fireworks

S1 E2: A ghost is reflected on the door of the elevator; A face of a ghost appears next to someone's feet on the train; A camera captures a ghost inside a cave; A person filming seagulls captures an apparition of a severed head on the deck of the boat; A dark shadow appears right next to a person juggling a soccer ball; An apparition of a man's face appears in the smoke from the fireworks.
