I have had dreams about earth changes, plus while awake and in contact with my higher self/spirit guidance I have received messages about changes. Rather than being given words, I am shown scenes where earth change like events take place, sometimes I find myself within such a scene.
Some of these messages have been about coastal changes. For example, one time while awake, I suddenly found myself on top of these big waves of the Pacific Ocean and they rushed towards what seemed to be the California coast. Then I experienced myself on the land and what seemed to be solar flares shot down to the ground.
When it comes to dreams, one time I was on the second floor of a small building watching TV, this building was located in a small desert town. Scenes of the desert around me being flooded were shown on the TV. I found this hard to believe, so I got up and looked out the window, and the desert around me was indeed flooding. Next I hid out so some unfriendly beings wouldn't get me, they didn't, and the unfriendly beings failed at their attempt to do what they were trying to do.
On another occasion I had a dream where Dannion Brinkley and I were watching TV (a near death experiencer who speaks about earth changes), he got up from his chair and said "it's hot in here, he stood by the window behind the curtain in order to cool off (he looked at me rather than outside as he did so), I got up and quickly walked to another window in order to open the curtain so cool air could come in, and I saw that a flood was headed our way.
I've received messages that difficult times will take place, but then things will change significantly for the better.
Here are a couple of links where near death experiencers speak about what they found out about changes. I believe it is important to consider that in some cases people might be warned about possibilities rather than eventualities, with hope that some of us will listen and change for the better.
