Dreaming of a watering hole is a sign of peace and rest, and if we also see horses or other animals quenching their thirst, its an indication that we will receive good news, a small inheritance or donation. If the trough we dream of is empty and dry, it predicts minor losses. But a trough is not the best place to quench our thirst, even though water may be clean, we must not forget that water-holes were created for animals, not for men. So if you have a dream drinking from it, be careful you are mistaking the path of happiness: meditate on this and look for other sources to quench the thirst of your spirit or the need for love.
