Matthew Manning, The Link: Matthew Manning's Own Story of His Extraordinary Psychic Gifts, Holt, Rinehart and Winston, 1974.

In Matthew's dormitory the disturbances were frequent and alarming. Heavy steel bunk beds moved of their own accord. Apports materialized and were propelled with force around the room. On one occasion fourteen table knives, origins unknown, were hurled against walls and beds. Broken glass, nails, and pebbles flew about, making sleep nearly impossible. Although the flying objects never hit anyone with force, they often missed only by an inch, veering off at the last second before impact.
