Reoccurring Theme Which I Learn Magic Options

I occassionally have dreams in which I was some kind of mage or magician there not all the same each time. More specifically a teacher of magicks. I remember in one I try to teach someone how to levitate, but he wouldn't listen to me. This dream of course followed others in which I learned other types of magic like phrases and written words as well as other abilities like walking through walls and using telekinesis, which I've forgotten and rarely dream about anymore. I found it kind of unusual, that what I learn in one dream and use that knowledge in another dream days later.

I don't practice magic in any way and most of these kind of dreams I dismiss. At the risk of sounding stupid and vague I'll stop here, but I am curious what people think.

The other day I dreamt I was in a lake. Everyone was swimming in it, but the lake had been poisoned and everyone rushed out. At that point I anticipated a wall of water like a tsunami to flood the lake. For some reason I was still wading in the lake and I stuck my hands down into the water. There was some blue orb forming in my hands and I started chanting a spell or something. The dream was pretty vague I couldn't remember the words. I did remember stopping the chant for some reason and thinking it was too long or I couldn't remember it all. But some voice inside my head continued saying it and from that point on I just repeated the words. When it was finished a wall of water shot out of the lake and high into the air. It turned out to be a purification spell of some kind because the anticipated tsunami didn't come. Unless I had anticipated the wall of water as result prior to chanting the spell. Man, my dreams are confusing.
