It's events in the form of dreams or memories, even thoughts that could reoccur over time if the now does not change. The now, can make the past seem like it was only yesterday or the day before. The years that go by, the months that go by, the weeks that go by, the days that go by. It's all in the past to the mind, but if the now does not change? The past can become all that is new.

All that it once was.
