Vanishing suddenly

So the first two dreams happened two nights ago but have not gotten around to writing them up here. The first one starts with me driving over a mountain and then parking outside a house. Across the street was a man and I got out of the car opened the back door and pulled out a baseball bat from the back seat. I started walking over to the man and he pulled out some crabs which he was going use use as weapons. When I got closer he ran away. I started hitting a wall and chipping off some concrete. I was swimming in a pool with a group of people. Someone through a knife and I had to duck below water to avoid being hit. When I came up the girl who threw the knife was laughing and said it was accident. I did not believe her but kept swimming in the pool. I turned around and ducked below water. I saw another knife fly above my head and I knew she wanted to kill me. I then felt someone standing on me and not letting me swim back to the surface. I became scared and started to panic because I was running out of breath. Then I woke up. Last nights dreams.. I started off in a prison or castle and I felt like I was playing a computer game. I crept into someone is room and started to steal things from the book shelf. When I took them they just vanished like they would in a computer game. I kept looking around the room and saw a gold skull. I zoomed in on one of the eye holes and there was nothing in there so zoomed out and zoomed in on the second. There were two red dots which I thought were spider eyes. I zoomed out and zoomed in on another hole in the skull. There was a black and white bug and he said, "I am going to hack you!". He then started to unzip his body. I zoomed out and ran to the window. I jumped out and rolled off the roof onto the street. There were many tall buildings and it felt a little futuristic. I started walking with a friend. The street changed into a main street of Adelaide and we were going to a club called "The City". We came past a bar and my friend wanted to go in. Hanging outside was another friend I have not seen for a long time. He had grown a very full beard. I was very happy to see him and started jumping up and down, shaking his hand and saying, "It is so awesome to see you!". We decided to go into the bar but a bouncer stopped us and asked, "How many drinks have you boys had". "3 or 4". I replied. "How can it be 3 or 4! You have either had 3, or you have had 4. Which one". It was said suspiciously. I said back. "We had 1 beer a few hours ago, then had 3, so it averages out to be about 3 or 4 standard drinks. I am not sure if we should say 3...or 4." Everyone was very impressed, and the bouncer let us in. The bar was quite classy. There were chairs going all the way round the main bar in the middle. We walked to the back and it turned into a Thai restaurant. The food was already per-packaged into plastic bags and the shelves were stocked topped to bottom with the these bags. I started to focus on a photograph on the wall of the inside of a bus. There was a dead body of a boy who had been shot. There was blood all over the bus. I could not stop looking at it. I was thinking to myself, that is a lot of blood for one person. And then I saw the driver was also dead and had been shot. I was then overlooking the bus as it drove out of control down a hill and crashed over the edge of small cliff.
