Ucfan35 – The first part is that you are in communication with your mother. Why that is important I do not know, but dreams are very specific.
However the storm is a very powerful influence to do with difficult times, but you felt okay about it and weathered it well. Such dreams are often about big changes that can occur, sometimes weeks or months ahead. The difficult times can be from within, like expressed emotions, or something outside of you such as events.
As for the spigot it may be an expression of great emotional energy, or life energy, being poured out, and the lamb or sheep are you attaining a wider vision of life and its meaning. The lamb is a special symbol meaning salvation in hard times. So it seems all will be well – and the sun will shine.
