What does it mean if a bird hits your front door?

Maybe, you have an energy to which birds are attracted. We don't know exactly how birds migrate, if they follow the atmosphere, or magnetic fields. High magnetic fields can kill a bird. Maybe the birds got confused by your energy, or brain waves, and they came into contact with high magnetic fields.

Maybe the birds felt like they wanted to die in their home, so they felt most comfortable with you, like your energy is most like home.

There is many theories that come to mind but these seem to be the most accurate.
