Transits of Neptune to your natal Mercury stimulate the telepathic and psychic functions of your mind. However, managing these transits can be difficult due to the disordered and chaotic nature of your thoughts. It is normal to experience distractions and absentmindedness. There is also a tendency towards deceit, delusions, or feeling overwhelmed by an excessive amount of indecipherable information.
These transits enhance your ability to communicate psychic and spiritual experiences. They give a special liveliness to your creative imagination and its expression. Your logical and rational faculties may not work as usual and may not be organized. As a result, these transits can benefit certain types of mental activity while impairing others. The impact ultimately depends on your natal Mercury.
These transits are favorable for studying mystical, spiritual, or metaphysical subjects. You will have a better understanding of these subjects when you simultaneously experience them.

I know somebody who passed his driving test when transiting Neptune was exactly trine his natal Mercury (which relates to getting around including driving). Clearly gaining his driving licence was a positive new experience which enabled him to let go of an old way of being (i.e. as a person who didn’t drive).
