i had a dream my coworker ate my lunch today, and I got angry
Dreams about coworkers can symbolize the relationships and power dynamics in your workplace. The fact that your coworker ate your lunch in the dream may represent a perceived violation of boundaries or personal property.
Your anger in the dream suggests that you may be feeling a sense of frustration or resentment towards this coworker, or perhaps towards someone in your work environment. This could be related to feeling taken advantage of or having your ideas or contributions undervalued.
Overall, this dream may be a reflection of your desire for respect and recognition in your workplace. It may be worth examining your feelings and assessing any underlying issues that may be leading to these emotions in your waking life.
