I'm just curious. One of my most frequent dreams was getting lost at school or being very late for a class. I had them all through high school and college (I'm a recent grad). In reality I always worried about getting lost or being late on the first week of a new semester when classes/classrooms changed. A lot of times in my dreams, if I tried to back track, everything would be completely different so I could never go the right way. This is probably the easiest dream I can relate to anything in reality.
