Dreaming of a burial means you are moving forward from your past and looking forward to turning a page to who you were. Regardless of what you may or may not have done yesterday, nothing matters more than how you tackle the present day. You get to decide whether your new page has value and adds to another chapter of life that you are the author of.
Take time to grief the past, and let it go. Put it away as a time capsule and bury it forever. It is not worth revisiting what was mediocre and forgotten. Rewrite the life that you have always dreamed about.
