Spiritual meaning of fasting
Fasting is a very old way of bringing about a change in consciousness,
and also a move towards self-realization through resistance to temptation.
It is considered to be the most powerful spiritual discipline there is, but
should not be indulged in in everyday life without properly qualified
support. Dreaming of fasting suggests that some kind of spiritual discipline
may be required.
Psychological / emotional perspective
Dreams while actively fasting can be particularly vivid or lurid. If we have
what we consider to be a grievance, self-denial may manifest as the image of
fasting (doing without sustenance). This may be the psyche’s way of making
this grievance known.
Deliberately depriving the body of sustenance in a dream may be an
attempt to come to terms with some perceived trauma, such as a lack of love,
or to draw attention to the need for cleansing in some way.
