The coffin

This dream started with me returning from an overseas trip and my friend who had kept my bags for me told me to jump off her 5 story bed, that it was safe.  I did so, and was convinced that I was safe, but I thought I might have died, I'm not really sure. Next thing it was my funeral and I saw my navy blue coffin being wheeled into the church. I somehow was in the coffin and out of it at the same time, desperately trying to shout at my dad that I was not dead and neither did I want to die. He did not hear me. A police officer came and told my parents that there was not enough evidence that I had died but they did not believe me and decided to put my in the ground anyway. I was buried alive.
