Sleep is biological creativity. The difference in how the brain handles learned information before and after sleep is the difference between knowledge and wisdom. Learning involves 3 steps for memory formation – 1. encoding 2. consolidation and integration 3. recall. Sleep is vital for the 2nd stage. The last 2 hours of our sleep is most critical for consolidation and yet our sleep is often cut short. Sleep physically changes the geography of memories. After sleep the location in the brain of our learning has actually moved.
