The best way to find out what Neptune will do over the next 14 years in your eight house is to first look back.
Over the past 10 years Neptune possibly attracted some people into your life who were in some ways creative and with whom you were able to engage in creative projects. Some of these people were possibly deceiving and misleading, but overall your healthy need to express yourself creativity probably attracted some honest souls as well (natal Neptune in 5th receiving a stimulus from your Moon and Pluto).
With the 8th house you will engage in projects which will seek more publicity and public attention. Typically when Neptune crosses into a new house, in the beginning (for about next two years) it doesn’t send a clear message and after it’s “anchored” it may make you feel pretty productive.
Hope this gives you an idea.
