OpenClaw has a feature called dreaming, and it is switched on from the start. Every night at 3 AM the agent reads its recent real chats, keeps the strongest notes in its long term memory and writes a short Dream Diary about it.

We have prepared a very nice guide for you, with a screenshot for every step:
