The paranormal phenomenon at BYU's Music Library centers on the Reading Room on Level 4 of the Harold B. Lee Library. Investigators and visitors report consistent auditory phenomena: moaning sounds that sometimes resemble unintelligible voices or distant talking. The vocalizations are described as non-linguistic sounds of distress or discomfort—moans rather than articulate speech, though some accounts note vocal tonality suggesting human origin.
Accompanying the auditory phenomena are extreme temperature fluctuations. The Reading Room is reported to experience either extraordinary cold or extraordinary heat—the room oscillates between environmental extremes without apparent mechanical explanation. No apparent heating or air conditioning activation accounts for the temperature fluctuations. Multiple independent witnesses report the same phenomenon, suggesting either a genuine paranormal manifestation, environmental factors producing consistent thermal anomalies, or psychological suggestion amplified by expectation.
In another section of the Music Library—specifically the Harp Room—a mysterious chair has appeared on the premises. The chair, dubbed the "Ghost Chair" by paranormal enthusiasts, lacks documented provenance. Library staff cannot account for its origin—it is not part of any acquisition record, donation, or inventory documentation. The chair simply appeared without explanation. Whether it represents a genuine paranormal object transportation, archival record loss, or an item of unknown historical origin remains unclear.
The Music Recordings Archives section—where extensive collections of old records are stored—is reported to produce unsettling psychological experiences in visitors. Students describe feelings of being spooked or scared in this area, though specific phenomena are not documented. The psychological discomfort may derive from environmental factors (darkness, isolation, atmospheric conditions, sound acoustics) or genuine paranormal phenomena.
The overall manifestation pattern suggests residual haunting phenomena or an intelligent entity manifesting through auditory and thermal means. Whether the phenomena represent genuine paranormal activity, environmental acoustic or thermal anomalies, or psychological suggestion remains contested.
