Grischkaja's world of dreams and mysteries

I don't know what is wrong with me, but my dreams are lately kind of weird.

Hours of sleep: 9
Recall: 2/5
Vividness:4/5

I'm standing somewhere in my old school waiting for someone. I already took my jacket of and hang it on a handrail. Next to me are tree taps. One of it leaks. I watch how it drops slowly. I'm wondering, why they are good for, because it seems that I'm standing in a floor or something like. I don't know why, but this leaking tap fascinates me.
Suddenly, there is more water flowing down. I try to turn it off, but it breaks and the water flows everywhere. I don't know what to do, so I go to an opened door. I knock and a teacher comes out. It's a chemistry teacher I've known. I explain to her what happened and she goes away to find a plumber somewhere.
While looking her go away, I remind myself that in fact, she died a year ago in a terrible car accident.
Yeah that's true. She just had began to work at my school when she died.
I find it really weird that she's there, but I don't get lucid, because obvious, she faded away. I start to think about it a time, but don't know what to do. So I simply walk in to her class.
I sit down somewhere at the back seats. There are some teenagers who are loafing around. I start a conversation, but I can't remember about what. In the meantime I'm taking notes about their opinions. It seems that I'm doing some work for university, but I don't know why or what.
After a time, I get up and go in front the class, like I did it- But I was learning to become a teacher in primary school and not at an high-school. Anyway, I just keep talking (I don't know about what) and the students are enjoying it
