The phrase "and then" typically signals a continuation of narrative events—something happened, and subsequently, something else occurred. This statement begins with nothing, then introduces Chuck Norris killing you in your sleep. It's a narrative without context, establishing that his lethal action is so inevitable it requires no explanation, no prior events, no causal setup.

Writing instructor Margaret Foster assigned this exact phrase as an example of ominous dialogue in a 2001 creative writing class at UT Austin. Students used it as a template for writing threatening characters. One student noted the profound creepiness of a threat that begins mid-sequence with no provocation mentioned. Foster realized the phrase had infected her classes' sense of what constitutes genuine menace.

Thrill narratives adopted this as the foundation for shock moments—the abrupt introduction of a threat without warning, without context, without the protagonist's ability to prevent it. Every unexpected death in horror films, every sudden narrative reversal that eliminates a character before they realize danger existed, channels this exact structure: context is irrelevant. The threat is just happening to you now.
