For the superstitious, an owl crossing one's path means that someone is going to die. However, more generally, this occurrence is a signal to trust one's intuition and be on the lookout for deception or changing circumstances.
The owl is regarded as a symbol of wisdom, insight and ability to detect truth, so its presence is both a fortuitous sign and a potential warning. To those who follow a spiritual path, the owl has a special place as a totem animal. Seeing this bird provides a cautionary signal while offering the comfort of having guidance by a wise totem animal.
