mental activity associated with the rapid-eye-movement (REM) period of sleep. It is commonly made up of a number of visual images, scenes or thoughts expressed in terms of seeing rather than in those of the other senses or in words. Electroencephalograph studies, measuring the electrical activity of the brain during REM sleep, have shown that young adults dream for 1 1-2 to 2 hours of every 8-hour period of sleep. Infants spend an average of 50% of their sleep in the REM phase (they are believed to dream more often than adults) a figure which decreases steadily with age. During dreams, blood pressure and heart rate increase, and breathing is quickened, but the body is otherwise immobile. Studies have shown that sleepers deprived of dream-sleep are likely to become irritable and lose coordination skills. Unusually frightening dreams are called nightmares, and daydreams are constructed fantasies that occur while the individual is awake. Studies have demonstrated the existence of lucid dreaming, where the individual is aware that he is dreaming and has a degree of control over his dream.

He distinguished the manifest content of dreams—the dream as it is recalled by the individual—from the latent content or the meaning of the dream, which Freud saw in terms of wish fulfillment. C. G.

 held that dreams function to reveal the unconscious mind, anticipate future events, and give expression to neglected areas of the dreamer's personality. Another theory, which PET scan studies appear to support, suggests that dreams are a result of electrical energy that stimulates memories located in various regions of the brain.

The DEAMS is re-engineering financial management activities across the board with a unified enterprise architecture.
DEAMS replaces outdated, unreliable legacy systems and processes with state-of-the-art, proven software to manage financial transactions and produce fully auditable financial reports.
The successful implementation of DEAMS should help address many of the limitations associated with Air Force's legacy financial systems and enable more accurate and timely access to critical information," said Eric Stange, managing director of Accenture's Defense practice.
DEAMS brings the lessons of private-sector business transformation to improving Department of Defense financial operations.
In short, DEAMS will make every dollar count by helping the Air Force more accurately and aggressively manage its funds in a way that can be fully audited.
The DEAMS Spiral 1 deployment represents a milestone in fielding warfighting capabilities using ORACLE's commercial-off-the-shelf Enterprise Resource Program, 11i e-Business Suite," Weber said.
The blueprinting process was capped by a series of workshops held in May 2006 to gather information from subject matter experts (SMEs) in order to refine DEAMS requirements.
DEAMS is also used by a number of support organizations including Defense Finance and Accounting Service locations in Limestone, Maine, and Columbus, Ohio.
The systems integrator (SI) selected will implement the DEAMS requirements including, but not limited to, the System Requirements Document, Process Flows and Narratives, the Requirements Traceability Matrix, and the Oracle product suite, The program is being implemented through the incremental development approach with versions that leverage commercial best practices to reengineer USTRANSCOM business processes.
DEAMS is a modern, integrated financial system for the Department of Defense (DoD) that will be used by the commands represented by the partnership that has the potential to be used by selected Defense agencies.
Beginning early next year, DEAMS will be implemented in several increments.
