The Gilcrease Museum is reportedly haunted by its founder, Thomas Gilcrease, whose spirit is said to be seen and heard wandering the grounds and building, making noises and appearing as a solid figure. He is not believed to be alone, as the museum is also said to be frequented by the apparitions of several young Native American children playing in the gardens and building. Visitors and staff have also reported unexplained footsteps, doors opening and closing, and laughter, all of which are thought to be the friendly spirits of the museum's past.
