I'm sure some pseudo-genius PHD psychologist character could come up with deep meaning...
I suffer with REM Sleep Disorder. We should definitely talk in meatspace if the opportunity ever presents itself. I know exactly what you mean, about your "weird" dreams. Some of mine tend toward themes of being "lost" and unable to "find my way home/the destination I'm seeking". Crazy stuff, and the REM Sleep Disorder vocalizations and parasomnic-limbic actions are pretty fucking amazing, I'm told.
I have two that have repeated... And they sort of fit that same model.
1. This one more when I was a student. I have not had it recently... I am in a bustling school... but no matter what hallway I go down I cannot find my class. And I am going to fail if I miss one more... and the branching hallways never end. And I never pick the right one. Ugh.
2. I am driving a car around a cloverleaf. You know that sort of 365 degree loop you might make to get on a highway. But I cannot see. My vision is growing dimmer and dimmer. And for some reason my hands cannot grip the steering wheel so I am progressively trying harder and harder to turn it to stay on the road (and BARELY pulling it off somehow!) with the constant threat that at any moment I could lose control and run off the pavement.
For me, the common themes in "nightmares" is not being able to perform a fairly simple task. And not being able to live up to the expectations of ______.
Have at it Dr. Freud.
