A 'sleeper' is a covert, non-official cover (NOC) intelligence agent who purposely develops a deep hidden cover or identity that is only compromised when there is an emergency or a direct need for that person's abilities and service. This happened to the author and for more than five-decades he was a sleeper with little or no knowledge of his past. In 2004, while being treated for PTSD because of his Vietnam War experiences his memory began to return and that is when it was realized that since age twelve he had been given a much deeper cover than that which he already knew existed. What is now known is that in late August of 1949 his mind and body were genetically and physically altered when he (and others) was abducted by extraterrestrials who were visiting Earth from another solar system. Also, he would later learn that an agency of the United States had authorized that change as well as sanctioned his later being recruited and trained as a US Army Special Forces and combat special operations soldier for the Central Intelligence Agency.
