It always happens the very same way in my dream, while my train is entering the station I think to myself that ok this is a station with a comparatively longer stopage but not long enough that I go out of the station to buy some wierd stuff or meet friends living in the city or I will miss the train. I also suddenly see sequences where I am interacting with my fellow passengers to whom I have been aloof all this while. The train finally stops, I get down, and straight walk out of the station, outside I am either in my old school, or college hostel, or any place which could not logically have been there. By the time I am back at the station, I can see the tail of the train smoothly gliding from the far end of the station. Sometime, I even run behind it and only once have I been able to catch it. Last night, in the dream, I asked an auto wala to take me to a nearest station so that I can catch the train there and we had an adventurous journey till the next station and I am able to catch the train.
Another, recurrent dream is I am in a place where the airport and the railway station are next to each other and I always go to the railway station thinking it to be the airport and this sentry has to direct me back to the right place. On reaching the airport, I always have lost my flight ticket and have to go to this glass counter where I need to talk to the concerned guy and convince him to give me a new copy of the same ticket looking for my name in their database. Having done that, I manage to just reach on time and then I dream of different things while I am in the aircraft.
Actually, come to think of it since childhood I have had a couple of such dreams which I keep coming back to time and again. I really really wish I could have their interpretations sometime.
