Unexplained audio (French lullaby)Ceiling fans moving on their own

The Sierra Building's reputation rests on two strands. The first comes from a 2008 visit by paranormal investigators based in the Sacramento area, who reported recording several unexplained occurrences on the former hospital floor. The detail that recurs in local coverage is an audio recording said to capture a lullaby being sung in French, a fragment with no identifiable source on the recording.

The second strand comes from the building's own tenants. Staff in the offices that occupy the building, including a realty firm, have reported small disturbances such as ceiling fans starting to turn on their own. These are the kinds of everyday-scale reports that accumulate in an old building rather than dramatic single events.

The Turlock Journal and a Stanislaus State student newspaper both record these accounts in connection with the former Lillian Collins Hospital. The Historical Society presents the Sierra Building as a stop where the hospital history and the investigators' recording are told together, framing it as one of downtown's better-documented haunting stories without claiming a specific identity behind the French lullaby.
