1132Agents write to their [memory stores](https://platform.claude.com/docs/en/managed-agents/memory) as they work, but these writes are local and incremental: over many sessions a memory store accumulates duplicates, contradictions, and stale entries.
1233
1334**Dreams** let Claude clean that up. A dream reads an existing memory store alongside past session transcripts, then produces a new, reorganized memory store: duplicates merged, stale or contradicted entries replaced with the latest value, and new insights surfaced.
