Ghosts in the temple

My father, Grandpa Keith Murphy, was raised in Salina, Utah. Salina is just south of Manti, so his mother, Alta Murphy, often went to the Manti Temple. He told us that on one occasion she took some of her children with her, and they stayed in the nursery while she did ordinance work in another part of the temple. While they were there, his brother, Dean, left the nursery without being noticed by the temple workers and went to explore. He soon came hurrying back, wide-eyed and breathless. He had seen all the people in white clothes and thought he saw a room full of ghosts.
