|Waking up can be a huge relief!|
It's not exactly a nightmare in the traditional sense. You aren't afraid for your life and nobody else is in danger... you're just put into some sort of every-day scenario that makes you extremely nervous and anxious.
For me, the two reoccurring themes for these dreams are school and stage.
I haven't taken a math class in almost ten years, and I still sometimes dream that I'm about to take some sort of math test and I don't know any of the answers. Similarly, I have dreamed that I have a huge project due soon that I haven't even started. School may be over, but the fear of failure that goes along with it remains.
I also used to act in high school, and sometimes I still have anxiety drama dreams. I'll envision that I have a huge role... I'm about to get onstage, and I haven't memorized any of my lines.
Recently I was blessed with both of these dreams in one night! I was actually laying there in a half-awake state afterward trying to figure out how to get the project done before I came to enough to realize that it didn't actually exist.
Having these anxieties still haunt me is a tragedy, but waking up to realize that none of it is real? That's always a great triumph in my book.
