To dream of classmates that you remember from school symbolizes aspects of your personality based on your most honest feelings or memories of that person. Ask yourself what qualities stand out the most about that person and see how that quality may apply to current relationships, or life situations. Are you thinking or acting in way that is similar to them?
To dream of classmates that you don't recognize symbolizes aspects of your personality that are exposed to the same concerns or anxiety as you. A thinking style or situation that may be noticing in yourself while dealing with a problem. The classmate's actions, words, clothing, skin color, or physical appearance can provide further insight.
Alternatively, classmates may reflect aspects of your own personality while you are attending school. Feelings about yourself academic performance.
Example: A young woman dreamed of a classmate kissing her. This classmate was someone who she felt used to be intelligent and then slowly revealed themselves to be unintelligent. In waking life she was having problems at University and her grades were getting worse. She initially believed she would do well in university and then was surprised to find that university was much more difficult then she expected.
