The Swallow
Scholars have said that seeing a swallow may indicate a faithful, educated, pious, and friendly man, and many swallows in the home might signify lawful wealth. It was said that swallows leaving one's home could mean relatives traveling away, and they are a good omen for work and movement, especially planting trees. It was also mentioned that the dreamer transforming into a swallow might indicate thieves attacking their home.
