2 Or 3 Time Recurring Dream Options

I have had a dream recently that ive had once or twice before, within the last 10 years. Its probably the most exciting dream ive had.

When it starts off, I'm being carried down a small river with a strong current, at first I'm in a rubber raft but this soon evaporates and Im just in the water without anything but my clothes. I also somehow know that the river will end to a drop soon so I keep trying to swim against the current or grab on to the sides, but to no avail (IMG:style_emoticons/default/fie.gif) (IMG:style_emoticons/default/fishing1.gif) Thie river by the way, seems to be in a large cavern or mountain, not out doors. As I look ahead I see the drop and am unable to avoid it. The drop is about a hundred feet and when i fell it was extremely realistic and my heart was pounding, I resurfaced at the bottom of the waterfall, and noticed I was still in the cavern, but about 200 feet ahead there is a huge gap in the rock and i see daylight, but no ground. Again i try to swim against the (now wide) river but i am carried to the edge and fall down the waterfall my last thoughts are oh shit.. ... (IMG:style_emoticons/default/yikes.gif) (IMG:style_emoticons/default/yikes.gif) The drop is at least 10000 feet and it was very exhilerating and realistic...I could see valleys and forests below but i never landed...after a few seconds of falling i was moved onto another dream. Any interpretations or ideas?

p.s. sorry if i rambled at parts or its hard to follow

Thanks a lot smasher, Im going to keep this in mind and hopefully become lucid the next time it happens (IMG:style_emoticons/default/laugh.gif)
