Strange dream woke up terrified?

Last night I had the oddest dream, first it started off that I was at my old house when I used to live with my parents, there is a river the runs by the property but the odd thing was they had a yellow submarine come out of the river, I got in the sub and met a Beautiful women but she was green and very tall, the trip didn't last long because I was back home and a giant glob of peanut butter started to chase me to the barn in the back yard, I raced to the hay loft and found a man standing there with a gun, I looked down adn saw a brick and picked it up to kill the man, I woke up after the gun shot went off and I had a huge pain in my chest when I woke up. The strange thing is how vivid this dream was and how I can remember every single detail and texture.
