What does it mean when an owl bites you in your dream?

Well according to the book "10,000 dreams interpreted" this is what it means:

To hear the solemn, unearthly sound of the muffled voice of the owl, warns dreamers that death creeps closely in the wake of health and joy. Precaution should be taken that life is not ruthlessly exposed to his unyielding grasp. Bad tidings of the absence will surely follow this dream.

To see an owl foretells that you will be secretly maligned and be in danger from enemies.

The book says nothing about an owl bite but here's what it says about bites:

This dream omens ill. To dream of a bite implies a wish to undo work that is pass undoing. You are also likely to suffer through some enemy.

This book has worked out for me, i hope it does for you, although in this case, it seems either way, your dream does not foretell happyness... I hope you can figure it out and that it turns out well.

Another response:

Owls in the most common sense are symbols of wisdom. Does wisdom "bite?" It could, if that wisdom reveals something that the dreamer would rather not know. The expression "sadder but wiser" says the same thing as this dream. For example, children are very happy believing in Santa Claus. As they grow up and realize that Santa Claus is make-believe, some children feel quite sad. That bit of wisdom was painful to learn. So your dream represents wisdom or knowledge that may be painful when you learn the truth.
