This dream occurred occasionally for more than a decade. From the 1990s into the 2000s.
I am in a white stone castle. I stand at the open gate to the the outside world. I want to cross but there is the massive crowd of people heading from right to left. I cannot cross. Then one night after maybe more than 10 years of real time, the dream repeats and the crowd part. There is a path directly across. I start to cross and the dream ends. The last version occurred a few times, but it seems to have stopped occurring.
