Does your boss expect you to be a mind reader too?

She's a terrible trainer, I had to learn everything on my own without any guidance. I am resourceful enough to do this, but she still just expects me to know what she's doing or thinking with no explanation and then gets pissy when I ask follow up questions. I try to go outside her whenever possible, but some things can only come from her. I am not the only one who has this problem with her, but her and I don't seem to mix well personality wise.
