What does a Class in a dream mean?

A class in a dream can represent:
Education
Learning
Life lessons
Can be a pun for not having enough 'class' in your mannerism and behaviour.
A class is a group of people with a common goal of learning something.
May represent the 'working class' status in society or 'blue collar' workers.
We also put things into different 'classes' to identify them more efficiently.
