Terrified of automatic doors

I have always been terrified of automatic doors, something about them just freaks me out. It is not an obsession, but i do admit i walk next to someone whenever walking thru them: including elevators.

Im not quite sure why, and i don't even kno if its unusual, but its true.

Also, I'm scared of all birds, to the point of panicing, and crying when they come near:)
