I agree that it's totally possible for our dreams to tell us things we don't know yet, as the above poster said. However, I don't think you necessarily have to take everything in them as a sign of something deeper. If you talk to this guy every day, it doesn't seem unusual that he would appear in your dreams. My dreams very heavily feature the certain few people I speak to the most often. If they keep happening and you DO get the feeling there could be something else going on between you two or in your life that's causing dreams like that, it would be worth investigating it further. (Maybe you should be friends? ) But if you really don't at all, then you don't HAVE to read into it.
