Had another dream about a magic academy of sorts, pretty standard fair for the most part.

I was someone who did have much experience with magic but had some talent for it, no formal education in it.
There were of course the types who thought I didn't belong there but would eventually get fed their words.
I remember living away from the school in some cabin with my mentor who was kind of magic user.
They could teach me a lot of things but my fundamentals were shite hence the school being needed, also social stuff.
I recall a specific trick he (it was a man) would use on people that came to bother him or us, he wore a hooded robe
normally and would have the hood up and suddenly use a spell that made him look like a skeleton and scare them off.
Thinking about it now he might have actually been a litch who used magic to look human most of the time?
I mainly wonder that as there was also a scene of him using some kind of acid spell to dissolve/melt something
coupled with the transformation in order to intimidate someone that had come by to harass us.
There was a lot more school stuff after that so part of thinks maybe I started living in a dorm?

All in all another random dream about some fantasy setting, I'll take these over zombie dreams any day.
