I'm always being chased by something. And I'm always with a team to combat what I'm being chased by (not literally always). The most interesting things that I have been chased by include dinosaurs, a sinister UFO, some weird colourful monsters, some FBI- type people and five robots that are each specialised for one sense and collectively hunt as a pack

It appears Rob that either you read to many comics or you watch too many sci-fi DVDs/Movies
Lots of dreams are influenced by what we see and do during the day. At night when the material is being 'processed' in our brains this comes out in the form of dreams.

Funny enough I also have dreamt of events which happened. For example I dreamed of the Concord the night before it crashed. I could hear the people screaming and bright flames burning, I knew aftewards because of the screaming noises of an jet engine which I clearly heard in my dream. Here's one dream which has not yet come true, I once dreamt of a huge rock which covered a large portion of the sky which crashed into the earth, this happened somewhere in America, this dream was so shocking that for days I was worried by it. For the earth was wracked with shaking like has never happened before, and a swirling cloud of dust enveloped the earth making it dark as night, there was debris hurtling wildly through the air, it was terrible. After many days the earth ceased shaking but the darkness remained. There was silence everywhere. I tried to move but was unable to do so, it was like there was a thick glass separating me from the destruction I could see. Then in the distance I saw a small light weaving through the darkness, it would disappear and re-appear again. It appeared to be getting closer. I could make out a figure dressed in white carrying a lantern on a stick. After peering to get a clearer view I could see that there was a long line of people walking behind this light and they were chanting. I strained my ear to hear what they were saying until I made out the words. "This is the day of the Lord, He comes like a thief in the night." Then I awoke screaming with terror. Surpised that I was still alive and in my bedroom.
