I have. Some times they have to be interpreted. Sometimes they are very clear and simple.
For instance, I had a dream I got on an elevator and could not get out. The next day I went to a job interview and afterward got on the elevator it went down a couple floors and got stuck. I was all alone. If I had not had that vision the night before I think I would have panicked. But I just thanked God for the warning, stayed calm and patiently waited for someone to get me out.
