Why would an owl attack a huge mammal like a human? Are you a particularly short person? Do owls attack other large mammals like deers, horses, bears etc? That's very scary.
But most owls nest in big threes high above the soil, so the probability of an attack is really low. Probably there was a fallen owlet hidden close to you.
