Supposedly it is an angel's sign to you, they are communicating with you sort of a "I'm here to protect and look out for you" or '"I'm here to help you"
It can also be a sign or communication from someone you love who has died.
It's usually associated with them saying "I'm ok" or "I'm here"
This may be too personal, but before my aunt Vickie died, my mom and her watched a movie about angels.
Of course, the angels in this movie didn't have wings. My aunt turned to my mom and said "angels have wings, don't they" and a few days later my aunt died.
The day after, my mom went out to get the mail which came early and heard my aunts voice clear as a bell say "angels have wings, don't they?" right as a white feather fell down right in front of her.
It gives me chills to even write this. if you're finding white feathers, an angel is watching over you.
