The opening sequence of Insidious establishes the setting and tone for the horror film. It begins with an unsettling establishing shot of a light turning into the family's house. Subsequent shots introduce the sleeping child and show shadows moving around the dark house. A shot of a pale woman's face lit by candlelight increases the ominous mood. The title appears in red letters with flickering lighting, suggesting danger has corrupted the home. A disorienting soundtrack featuring violins builds tension and leaves viewers feeling uneasy throughout the sequence.
