Hi sassy,Neptune conjuncted my ASC years ago and it's STILL in my first house for a long time to come. (I have a huge first house, Aquarius intercepted in it) Right now it is opposite my Mars, that part sucks.
You can expect to become more intuitive, artistic, have vivid dreams, become more spiritual, compassionate towards others, have a more vivid imagination than usual. Occult matters will appeal more to you. Pay close attention to your dream life.
You will confuse both yourself and others about who you really are.
This is a long transit, so be prepared.
You can learn a great deal from your dreams, if you pay attention. You can learn alot about yourself. You will be on a journey of self discovery.
And the most annoying part of it all!!! You can at times be very flakey, and "out there".....no matter how many earth planets you may have to keep you grounded. Trust me.
Hope that helps.
