A flashback is a narrative technique used in movies and stories that interrupts the normal chronological order of events to show something that happened earlier. Flashbacks provide context and background about characters by revealing past events through dreams, memories, or scenes from the character's younger days. They are used for both comedic and dramatic effect to give insight into a character's motivations or contradict something claimed in the present.

1.  A flashback is a transition in a story to an earlier
time, that interrupts the normal chronological
order of events. A flashback in a movie might
show what happened when a character was
younger.
 Flashbacks are often used for comedic effect, to
prove or contradict something in the present. For
example, if a character in a sitcom claims he does
the dishes every single night, flashbacks could
show him ignoring a giant pile of dirty dishes on
various occasions. Flashback can also mean a
sudden, vivid remembrance of past events, like
having a flashback to your kindergarten days if
you go visit that classroom today.

2.  Flashbacks are interruptions that writers create
to insert past events in order to provide
background or context to the current events of
a narrative. By using flashbacks, writers allow
their readers to gain insight into a character’s
motivation and provide a background to a
current conflict. Dream sequences and
memories are methods used to present
flashbacks.
