👉 Collected means "collecting something you've collected" in the colloquial sense. Consider a situation where someone has been collecting toys for years and suddenly decides to donate them all:
Example: She bought tons of new toys, but then decided she didn't need any more. Then she gave away all her old ones to collect things. This word is used in an edgy or unsettling context, as it implies the person might be delving into a deep secret about their personal collection.
