What happens to Memory when the Conscious Mind stays focused on the Here & Now?
One thing that happens is that Memory ceases to function as fully as it once did. Short term events are easily forgotten or better stated, are not easily recalled. Dream events happen, yet the Conscious Mind has difficulty recounting them, even though it was easily done before.
The Conscious Mind is aware, but not conscious of, the Dream World. This may seem confusing until you realize the Dream World is where the SubConscious Mind / Higher Self plays with the Imagination and creates the Future. Memory deals with the Past.
The Past and the Future - Memory and the Imagination - are not functions of the Here & Now Consciousness.
