I had a dream a few weeks back that I was in college again (I'm ten years out of college), and I'm taking an advance math course. I am usually confident in math, but when I realized that I didn't understand a word the teachers and other students were saying, I knew I was in over my head and probably in the wrong class. I realized in the end that I took a class for electrical engineers and dropped out. What do you think this could mean?
Good morning, Maricel.
What you've described here seems like a fairly common anxiety dream. The setting is college to reflect the situation you're in - one in which you need to learn something. Your mind chose a math course specifically because of your confidence in that subject - this is saying that your self-confidence is low right now. Language barriers happen in dreams because of communications barriers in waking life - the situation this dream references is one in which communication is low or non-existent.
The decision to drop out is the crucial factor. It points to what you believe is the best solution to the problem. If the rest of the dream refers to a relationship - personal, professional, or whatever - then this part is saying to you, this isn't the relationship you thought it would be - better to cut your losses and get out now.
