It's definatly normal!! I hate doing any presentations as well, but I understand it's just something we've got to do. But if I know my supervisor is coming, it goes up about 100 points on the scary scale!!
But the up side is that it is always ok. whilst it does give you an extra dose of the nerves, It's always worked out fine. Even presentations that i've done that I thought went awful, if he was there, he always says afterwards, that was good, well done. And that tiny little bit of feedback makes it worth it!
good luck, but don't worry, you will be great x
