In one story that haunted Twain for much of his life, he and his younger brother Henry secured jobs on the steamboat Pennsylvania in 1858. On the night before they went aboard, Twain dreamt that Henry was dead, lying in a metal casket wearing his older brother’s suit. In his hands was a bouquet of white roses with a single red rose in the middle. The steamboat’s journey commenced, but due to a disagreement with the pilot, Twain was transferred to a different boat while Henry stayed on the Pennsylvania. Shortly after, the boiler exploded, killing Henry. The women who worked at the funeral home were so moved by young Henry’s innocence and beauty that they gave him the most expensive metal casket and a borrowed suit. When Twain entered the viewing room to see his dead brother he was shocked by the uncanny resemblance to his dream. Then, as he mourned, a woman came in and placed a bouquet of white roses on Henry’s chest, then pulled out a red rose and placed it in the center of the bouquet.
