I had a dream that I was being severely bullied by classmates in high school. What is the meaning?

I'm 28. I was not bullied in school but was very shy and didn't stand up for myself when someone made fun of me. I recently quit a job where I worked with mostly men who were indeed bullies and treated me like scum. Once again - I didn't stand up for myself. When I woke up from my dream I was so upset. The bullies were telling me I was ugly and fat. I am currently overweight and feel very depressed about it. Is it all just a combination of these life experiences?
