Probably something to do with dust from the Sahara or another desert. It tends to colour the skies red with a dusty film, and this alters how celestial bodies appear to the human eye. As for something big, affirm that SOMETHING BIG IS HAPPENING, rather than is gonna’ happen. The Universe takes things literally.
SOMETHING BIG IS HAPPENING: affirm that a good many times and then see how the Universe manifests it for you. Something big and positive, but relevant to you and your unique life. Think how exciting that would be.
Every year there tends to be something like this: a blood moon or a super moon or something like. I have heard that these are very good times to make intentions to the Universe, so have an intention ready (drawing, list, vision board etc) for when one takes place.
