almond quartz

I dreamt I was taking some sort of class. The man was rattling off sentences we had to create based on subjects. Sounds easy, but in the dream it was challenging. I was listing the subjects quite quickly and I couldn't write them down fast enough. I told someone sitting next to me .. that this was nuts. How does he expect us to get this done. I heard one of the subjects that stuck in my memory. Something about almond quartz. I had never heard of almond quartz before... how was I supposed to write an intelligent sentence on it? I just happened to have an encyclopedia in my lap. I looked up almond quartz.. it had been discovered by a Dr. Almond, but the book didn't list any of the qualities about it.
