Maybe you can start with doing seminars and small workshops on your topics to guage the interest. Then those students could be prospects for coaching if they want more personal and in depth help.

This way you can see if there is really interest in those topics. You could do all of the above, even the Dream Interpretation and Tarot ideas. Because they will all be separate seminars, it wouldn't matter if one person would be turned off by the other topics. Market them separately to their respective markets and just go from there.
