Black cat crossing your path
One of the most popular and oldest beliefs, this one is attributed to various sources. One version goes that black cats forebode doom; another goes that black cats are demons in disguise; and yet another goes that they were once pets of witches that turned into witches and hence they are witches in disguise.
Contrary to worldwide beliefs about the black cat, the Japanese consider a black cat lucky.
So the next time you see a black cat you decide whether you want to turn back or walk ahead.
