A few nights ago I was extremely stressed and having bad anxiety when I was going to bed, I had a dream where I jumped into a lake, but apparently there was a concrete slab chained to me I didn't know about? And once I got to he bottom I was like paralyzed. I was trying to swim back to the surface but was weighed down and I was reaching up and I felt extremely scared, I woke up and I felt really heavy and the dream was just stressful. I also was thinking "maybe I'm dreaming" but then threw that thought away when I couldn't reachthe surface. Do you think this is a metaphoric dream on how I was trapped in anxiety when I went to bed?
