I have action movie dreams like you guys are describing, too :) I've only been a vampire in one, though; usually I'm a vampire hunter. For a while in college I had recurring dreams about being chased by either vampires or Great White Sharks. Don't have those as much anymore, but every so often. Have the secret agent dreams like Rosie is describing, too :) Since the War on Terror started I've also started having dreams about terrorists. Had some weird dreams during the Iraq War. Here is one I had March 13, 2003 (a few days before the war started) that I emailed my friend about:
I just woke up from a very vivid dream about a coup in Iraq. I and an audience of hostages were watching a closed-circuit TV of Saddam and about half a dozen bodyguard. I sensed Saddam's time had come and mentally "pushed" in that direction. Saddam snapped, grabbed a machine gun, and started shooting his own guards. He was dragged off-camera and the TV went out for a second. When it came back on it showed the Republican Guards executing Saddam. My and the audience's first reaction was skepticism that it was really Saddam rather than a staged death. As if in response to that thought, a member of the Republican Guard held Saddam's severed head to the screen. His face (looking in bad shape, reminiscent of the picture of Khalid Sheikh Mohammed after his arrest they've been showing lately) had been half burned off, but it seemed to be him. The Republican Guard member seemed to be possessed by the Devil, and a realization flashed through all of us of that these people were as inhumanly brutal as Saddam and they were now in charge of the country, putting resistance members in great danger. A couple of us snuck away to a warehouse to find weapons to overthrow the Republican Guards. At that point the dream started moving onto other topics.
Then about a week later, on March 23, I had this dream:
I had another weird dream about the war last night. In this one I was part of some group advancing on an Iraqi palace. We got inside and took the palace without much resistance because the enemy had disappeared. But once we were inside, I started to wonder where our enemies had gotten to. I got a bad feeling and decided I'd better look out the window. First I saw that the building was surrounded by an army of giraffes (!) coming out of palm trees around the perimeter. Behind the first wave of giraffes came another wave mounted by Arabs. They crashed through the building from all sides. I tried to warn the others but there was no time, so I tried to find somewhere to hide on another floor in the building until I could figure out a plan of counterattack. Mounting a giraffe of my own to get away, I got all the way to the top of the building (which was an Arab prince's bedroom), and couldn't find anywhere to hide, so I came back downstairs with the intent of either fighting my way out if possible or surrendering if not. When I got back downstairs I saw from a distance that there was some type of meeting in the main room of the building, and it wasn't clear who was now in charge of the building, us or the enemy. I woke up before I found out.
A few months later on May 18 I had this one, which really freaked me out:
I was jolted awake a few minutes ago by a nightmare that WWIII had broken out between the US and China. I was in this building with a group of people talking to Abraham Lincoln, who was a great covnersationalist--he was showing us what his old 1800s study Bible looked like, it was very cool. Suddenly we noticed everyone in the room running for the windows--something going on outside. We all went out to look and a crowd had gathered in downtown Milwaukee on the shores of Lake Michigan. Something was very wrong--the sky changed color in places--jets?--bombs? "They found an h-bomb," I heard somebody say. Suddenly machine-gun fire hitting the area between the lake and where we were--Chinese troops advancing out of nowhere, too close for us to escape. Some of us were trying to figure out a way to get away and were about to run when we heard a speakerphone behind us boom out, "Retreat!" I turned and US troops were coming from behind to reinforce us. We were caught in the middle. It was about to hit the fan. . .
Those are some dreams I've had which make me agree with you that "Some dreams are way too realistic"! Forutunately ones that intense are pretty rare for me. More often it's just some mild action scenes.
