During Mercury retrograde you may feel the overwhelming need to address something from the past that you chose not to speak on for whatever reason. During retrogrades things from the past that have not received proper closure tend to come up so they can be dealt with. If it’s not you, then you may find that someone else will bring up something from the past for you to deal with. They may even reveal some parts of the puzzle that you didn’t have before. This does not have to be anything ominous. These are just things that should be dealt with so that you can move forward.
More information on this Mercury retrograde can be found in my previous post 08/7/17 Eclipse Season
