Third Man factor
The Third Man factor or Third Man syndrome refers to the reported situations where an unseen presence such as a "spirit" provides comfort or support during traumatic experiences. Sir Ernest Shackleton in his book South, described his belief that an incorporeal being joined him and two others during the final leg of their journey. Shackleton wrote, "during that long and racking march of thirty-six hours over the unnamed mountains and glaciers of South Georgia, it seemed to me often that we were four, not three." His admission resulted in other survivors of extreme hardship coming forward and sharing similar experiences.
In recent years well-known adventurers like climber Reinhold Messner and polar explorers Peter Hillary and Ann Bancroft have reported the experience. One study of cases involving adventurers reported that the largest group involved climbers, with solo sailors and shipwreck survivors being the second most common group, followed by polar explorers. Some journalists have related this to the concept of a guardian angel or imaginary friend. Scientific explanations consider this a coping mechanism or an example of bicameralism. The concept was popularized by a book by John G. Geiger The Third Man Factor, that documents scores of examples.
In Geraldine McCaughrean's young adult fiction novel, The White Darkness (2005), the teen-age heroine, Sym, joins a doomed Antarctic expedition. Abandoned and lost, she is guided to safety by a "third man", her imaginary friend, Captain Lawrence Oates.
In Larry McMurtry's Western novel Lonesome Dove (1985), Pea Eye, after surviving an Indian attack with Gus, makes a trek back to Call and has an experience of a "ghost" or "spirit" that guides him during his walk.
