When I dream of the end...there is always rushing water and people (who I have never met before) are hanging on the sides of mountainess rocks, trying to climb to the top, and there is always a curve in the path of the water leading to no where except a tunnel. I always wake up before the end of the tunnel.
I find it easier to "break down" dreams to find the logic in them. The important thing to do when you have a dream like this is to make it seem like something (to almost make an excuse) that you can deal with to make it easier for you when the dream occurs.
I have had dreams that made me afraid to go to sleep, and that is why I make "simple excuses" for them to live with them better and not stress over them so much. I wouldn't be surprise if your dreaming about this dream when it leads into another dream...as a part 2

. This has happened to me as well. Please let me know if this occurs. Thanks.
Hope this helps.
