Tide pool
A small pool of seawater left behind by the receding tide — a complete world held in a rock basin between two tides.
A tide pool in a dream is the dream's image of a complete world held in a rock basin between two tides. The pool is brief; the next tide will refill or empty it, and the creatures in it are tuned to that rhythm. The dream brings the tide pool when something in your life — a small self-contained community, a project with a known end date, a friendship inside a specific season — is being lived inside a container that has a structurally limited life. A tide pool tended with awareness of the coming tide is the dream affirming the honest temporary world. A tide pool treated as permanent, with the inhabitants surprised by the returning sea, is the dream noting that the temporariness of the container was forgotten, and the change will arrive on schedule regardless.
