A measure in dreams whether of capacity, length or weight suggests a comparison, often against some kind of spiritual standard. Emotionally, when we attempt to find some kind of tranquility we will measure it against previous experience. In dreams this may come across as an overflowing cup, gauge or measuring stick. In waking life, we will try to measure our performance against correct practice or a set standard. This will surface in dreams with actual physical instruments of measurement such as rulers, scales and other measuring devices. To be measuring standards is to be applying a preset code of behaviour.
