Poutnik,
I can tell you with certainty that you have an ability to contact your teacher.
Everyone has his/her spiritual guide/teacher, but they do not interact in this tonal level.
Teacher finds us when we are ready

..You just dream on and meditate, or do whatever spiritual practice you do regularly and guide/teacher will reveal itself. We all have guides there, it is only a matter of time when will they show their presence.
As we get more opened to them, as we see more, they see that and come. They may even be always with us, but we mostly can't see their presence, because we aren't opened enough.
Sometimes you can surely feel a presence, but you can't see it. That might be your teacher, spirit that is leading you and whispering you some suggestions and advices and some good decisions we make are the result of their advising.
We get opened to them by spiritual practice; meditation, aware dreaming...awareness expanding in general.
There is no rush for such a things. Years can pass in the beginning from one till another meeting.
I have met my guide in black cloak in 1999., but I saw him again in the beginning of 2001., and only for few times. He started to appear more frequently in 2003/2004, because till then I got more opened.
And..I agree with Dreamster. Calling a Goddess is like calling a master of creation, so weather you call Goddess, Master, God.. whatever, as long as you feel a true link with it, you will get an answer, or presence.
I spontaneously call ''Master!'' there and I get an answer each time.
Finding teacher in tonal is a bit different thing. Teacher in dreaming can be the one you have in tonal, but it doesn't necessarily have to be. You can have one teacher in tonal, but more guides in dreaming. For me it was a bit tough to find a teacher in tonal. I had bunch of them in dreaming, but in tonal it was not so easy.I was saved by patience. I meditated and dreamed and it happened all of a sudden that I dreamed with a man and then later I literally run into his meditation courses, and that is how it all begun.
Just don't worry, nor force it, it will happen, and until then, you relax, meditate, dream aware, and get your life as more as you can in balance.
Best wishes to you,
Castor
