Subject忽然Verb/Verb phrase

Meaning (意思 yìsi)

忽然 describes an action that occurs suddenly, unexpectedly, and within a short span of time.

Explanation (解释 jiěshì)

The adverb 忽然 is used to describe an event that occurs very quickly, abruptly, and unexpectedly. It is equivalent to "suddenly" or "all of a sudden" in English.

忽然 always precedes a verb or verb phrase. It is commonly used in narrative writing to create a sense of surprise. Compared to 突然, 忽然 can only function as an adverb, whereas 突然 can also function as an adjective (e.g., 这件事很突然). When used as adverbs, the two are very close in meaning.
