Neptune is the planet of illusion, lies, addiction, toxic relationships, and all things that may have looked good in the beginning, but are actually not. Retrograde periods are the time when this enchantment slows down and reality settles in. It is a good time to examine whether you've been living in a fantasy world and should wake up, or whether you've picked up a bad habit or addiction. Neptune retrograde periods increase sensitivity and compassion, while may also increase anxiety and guilt. It is also a good time to self-reflect and perform meditation or self-improvement.
