Returning swallow
A swallow coming back in spring — the return of a presence whose absence had been quietly accepted.
A returning swallow in a dream is the dream's image of a presence coming back after the winter you had stopped expecting it from. Swallows leave for half the year and arrive again on the same gable; the return is one of the small annual proofs that absence is not always the end. The dream brings the swallow when something in your life — a friend, a season, a working version of yourself — is making the return journey. A swallow back at the old nest is the dream affirming that the thread held. A swallow that does not arrive the year you expected it is the dream noting that the return you counted on has not happened, and the gable is going to stay empty for the season.
