Yeah, I've found that if I dream of a tsunami or flood, or volcanic explosion, its likely to involve a deep-seated emotionally charged issue that I become aware of and have to work through. Just recently I dreamed (over 3 nights) that I was on a ship that was sinking - but that I just escaped before it did. This one manifested as a physical reaction (vomiting).
Like montalk says
The more enthusiastic, detailed, and frequent the buzz about a movie, the more likely it is make it. I think the future exists with the present and past, but we still have choice in which particular future becomes the present.
Sometimes I dream about world leaders as if I'm in the room with them. Its often been followed by some world event happening. But it can also represent a part of my consciousness that's "in charge" that needs looking at.
Three nights ago I dreamed about being in a room with Bush (argghh!!) who looked old and had grey mascara on. I felt as if his house was going to be bombed. I managed to escape past some intruders. I discovered some british soldiers outside who I ran to feeling relieved, only to discover they were the ones attacking Bush.
On waking, I wondered if something was about to happen in the world arena - but now I've just realised it was a preview of me looking at an outworn controlling authority-figure pattern, that I'm working on 'bombing'! I wrote about that part at: http://forum.noblerealms.org/viewtopic. … 186#p38186
Well, that turned out to be a bit of dream analysis on-line. Sorry about that, but I'll leave this in case it gives any clues to anyone in dream interpretation.
(But wouldn't it be funny if the Brits turned over a new leaf and bombed dear old George W?)
