Hmm... Buddhism in general does not encourage dream
interpretation.
If you want to continue to be a devoted yogi, generally you
should never cling to dreams. If you do, you will eventually expose
yourself to the influence of the four maras. If your dreams are
positive, do not have any expectations. If we are filled with hopes
and expectations, even positive things can turn negative. If your
dreams are negative, don't take them too seriously. Learn to see
negative dreams as illusion, not real. Then, although a dream seems
negative, because we realize that it isn't real, it becomes a
positive thing that prepares us for further development and
realization in the spiritual path. This is the practice of a
yogi.
