I was running down a nighttime street from a shadowy black van that kept stalking me. It was around every corner I took and eventually caught up as the black figure in the van almost killed me
Running in dreams often symbolizes escaping from certain situations that you might be facing in your waking life. The black van that is stalking you in the dream could represent something that is causing you fear or making you feel unsafe. It is possible that you are trying to run away from a problem or a situation that you believe may have a negative outcome if not dealt with properly.
The fact that the van catches up to you and almost kills you could indicate that you feel overwhelmed by the situation in your waking life and fear that you won't be able to handle it. This dream could be a sign that you need to face the issue head-on instead of trying to avoid it or escape from it. It may be time for you to take control of the situation and find a way to resolve it so that you'll be able to move on.
