Strange horrible dream

I'm not back in school yet-I will be starting in a couple weeks, but that's what this dream was about. I was probably in my advisors office and she was talking to me about my choice of major. She gave me this weird look when I told her what I was planning on being-an anthropologist. She then must have said something about how she didn't think I could handle it. I said that I thought I could so then she decided to submit me to some "tests." She had me follow her hand as she ran around the room and said that if I took my eyes off of it, then I had failed. I kept watching, but I must have been drowsy and maybe dizzy so I closed my eyes for a moment. I didn't think that she had noticed my slip up because she went on to the next test. She then started writing words on a chalk board, but they were cursive, upside down, and backwards. She then told me to figure them out as quickly as I could. I just told her it would be easy because I used to figure stuff like that out all the time as a kid. As soon as I looked at the board I realized my mistake. The words were constantly changing and I couldn't figure them out fast enough. I had this horrible feeling of dread in my stomach and for the first time doubted that I really could handle my chosen career. This woke me up and even now I'm not sure if it means anything or it's just nervousness over the semester starting. What's weird is that I didn't think that I had given school much thought since I signed up for my classes. At least it wasn't a work dream, though, those freak me out bad:)
