Dreaming that someone is a teacher when they are not in real life can mean that, to you, they represent:
- An authority figure—someone or something in your real life who you allow to have some power over you in some way
- Someone whose opinions or advice you listen to
- Someone who has taught you something in real life, or whom you would like to do so
Dreaming that you are a teacher when you're not in real life could mean:
- You feel your insight would be valuable to others
- There is something specific you'd like to teach or explain a certain person or group
- You desire to feel respected or looked up to
- You're wondering what it would be like to be a teacher (and so you're trying it out in the dream state)
