“I think this dream is so profound, and some of the themes are becoming common in our dreams. My interpretation is: The train station waiting room is I think a place between the realities and dimensions, and so far the train has not come, and the only portal takes you back to the regular world, where when you go back it is clear you are no longer normal–the sign tells the people you “have awakened” and they do desire that, secretly, but the only thing they know to do with that desire is to be sexual with it. Luckily the silvery/white light protects those who revisit the regular world. There really isn’t much else to do until enough people have assembled in the train station and the train does finally come.
   
There’s a tribe, not really active now, called “I Have Awakened – Now What?” — this is the feeling I have had for a long time now. Waiting is so long and so dull!“
