Dreaming of crows

All symbols in dreams have an origin, so there are no arbitrary symbols. In the case of the crows, it is a sign that comes from the ancient Norse religion,

in which he narrates that the god Odin had crows that informed him of everything that happened in the world, so that if in a dream a crow is crossed or we see crows flying in a circle, it is a warning, as when the crows told Odin that an enemy prepared bad actions against him. So in this case we must be prudent and not do risky things that our enemies can take advantage of to harm us. Although there is also some symbolism related to something that happened during the bubonic plague, when the crows devoured the eyes of the corpses, which is why sometimes they are associated with death. But the symbol that dominates most is that of Odin's messengers.
