blast from the past
Unexpected memory trigger
A blast from the past is something—a song, photo, person, or experience—that suddenly brings back memories of an earlier time: Hearing that song was a real blast from the past.
The phrase suggests pleasant nostalgia rather than painful recollection.
Often used when encountering something unexpectedly: Running into my college roommate was a blast from the past.
