Dream (from dream diary)

I was with them now, and initially felt at ease with the situation. We were going somewhere, trying to find a place on foot. Somewhere in a green space, like the Greenway with hills/grassy slopes to each side and a path through the middle.  We went up a small slope. I think there were train tracks next to or near where we were walking so I was conscious that a train could come. The ones I was with may have briefly been replaced by a man who may have been my beloved.  At the top we had two directions to choose from.  I wanted to go the less interesting looking way.  I felt that would be easier so they agreed that I should have a quick check of it and report back.  I had to squeeze myself through a space with railings/metal banister type things but decided that this in fact was too difficult so said we'd go the other way.  Not sure of how we got to the inside of a building where they seemed to know where they were going and darted off, telling me we had to make a run for it.  I knew it was somewhere we weren't supposed to be and was trying to look around to get a feel for the place but they'd gone out of view and I heard someone coming so quickly followed them.  Just managed to see them go through a doorway and immediately drop down a kind of laundry chute.  I was too scared to hang around to see who was coming but equally as scared to go down the chute and they'd already gone about 1 minute before me.  I made the snap decision to follow and threw myself down.  I thought they'd be there waiting for me when I landed but I think they'd continued and I was left in a place with an extremely low ceiling, in a type of darkness - as if I had my eyes closed in the half-light - feeling like I was trapped here and suffocating.  I knew that there was no way out and that no one knew I was there.
