My wife and I were dropped off at Julie's house for a computer course. Julie was a computer expert where I worked that I had known for some years.
Of course, in real life she did not give computer courses in her home.

We arrived early and were taken to Julie's family room where there were
computers set up on several small tables all around the room. We got ready and chose our computers and others arrived and we all learned much in the course. Then it was time to leave and we had no car(I could not yet drive because of a serious operation I had went through recently), so we asked Julie and she got her son to drive us to a bus stop. He was about 20 and clean cut. Then I awoke.

A few days later I was in Julie's office, and I told her about this dream and told her that I had no idea what it meant and neither did I know if she even had a son. She told me that she did have a son, who was grown up and lived in a state many miles away. What does it mean?

The part about the computer could have to do with you needing information about something. < /br>
Being a passenger in a car can have to do with feeling that someone else is controlling things. Maybe you don't have control because you don't have the information you need.

Lots of people have sons (every man is/was somebody's son) so Julie having a son in the dream and in waking life could just be a coincidence unless there were strong similarities between the son in the dream and the son in waking life.
