Recurring Dream: Blindness
For about a year now, every now and then I'll have a very peculiar dream. The details are always different, but it usually involves me running around, fairly excited. Then, after I've been running for a while, I'll go blind suddenly, or my vision will get very bad. In most of the dreams, when I stop running, this goes away. This is always very frightening and irritating, and I'm always quite relieved when I wake up and the problem is gone.
I just wondered if anybody has an idea as to what this might mean.
Note: I'm a 19-year-old male with a history of anxiety.
