Crows and Ravens.

Anyone else notice when crows or ravens fly over you, something bad happens?
Every time I go outside(which is rare), crows/ravens will sometimes fly over me, and shortly after something bad happens(anxiety attacks, misunderstandings, etc.) almost every time.
I just assume they're migrating, but they always show up before something inconvenient or bad happens.

Maybe its a delusion, but anyone else notice this?
