my school dream

This was the dream as I was waking up today.

I was in the high school in my home town. I couldn't remember my schedule, then I couldn't find my classroom. I was going up and down the 3 levels and looking in all the rooms. Finally, I found a class where the teacher let me join in, even though it wasn't my class. She gave me a book. It was the English book I had in 7th grade. The class was set in the art room, but the class she was teaching was anthropology.

When class was over I went to my locker, but couldn't remember the combination to the lock.

Then I went outside to drive home and remembered that I was supposed to take the bus. But it was too late, I'd missed it. (In real life I used to drive to school and take the bus home because I'd forget I drove. :oops: )

Lots of forgetting. The meaning of this dream should be obvious, but it's not.
