7. Memory Storage

We take for granted just how many things we remember, but our capacity for storing memories is quite remarkable. We are even able to recall memories from when we were young, and at an instant. In order for us to be able to access these memories, however, we must first be able to process them.

Dreams are thought to be caused by our brain processing events so that they can be stored away for safe-keeping until they are needed at a later time. Doing this in our sleep might mean that the brain is able to focus on the task of processing information without interference from the outside world.
