anatomy of a dream (III)

I was landing on a plane, got out of it into the airport terminal. Was supposed to go catch another one - think I was heading to Copenhagen. I didn't know the airport though. Anyway. I was walking in the terminal when I passed by a security check and the lady who was there told me I had to wait. There was something going on and the Airport Security Authority - or whatever entity - wanted to see me. I remember checking the time - was going to miss the flight - and then I realized I had forgotten my backpack in the previous plane. The lady told me that it was probably the reason why the authority wanted to see me: to give me back my backpack. After this point I woke up and intentionally returned to sleep several times - around five - only to see if I could catch up with the dream and see what did they wanted with me. Everytime but one, I was there, in the airport terminal, waiting. I was automatically catching up with my own dream, which consisted in waiting in some airport.

In the one dream fragment in which I was not waiting, I was in a interrogation room. My backpack was nowhere to be seen; but they had a spray can that apparently was mine. The security officers opened its bottom and took from there a small plastic bag that contained a white powder. I was surprised, and explained them it couldn't be mine. They believed me and let me go.
