David Hall at Concordia University (Nebraska) is reported to be haunted by Native American spirits, with experiences including unexplained noises, appliances turning on and off, and sightings of a Native American woman and man. The hauntings are linked to the discovery of 18th-century Native American bones during the hall's construction in the 1970s. Students report hearing and seeing appliances, like hair dryers and curling irons, turn on and off by themselves. Showers are also said to turn on and off without anyone present. The most cited apparitions are a Native American woman and a Native American man. Some reports mention seeing the Native American man in a dorm or appearing at the end of the stairwell. The activity in David Hall is connected to historical findings during the dorm's construction. Bones, identified as 18th-century Native American remains, were discovered in the ground beneath the building.
