Strange Experience

I had a strange dream last night. I have seen all the people I have met and all things I have the done in my life during this dream. Moreover, I have experienced my death, I was scare full because I was thinking what would happen for me after dying and I could not realize. I have always though death is something really usual and natural but what I have experienced was frightening. Where I was going? What would happen to me? After that, I dreamed I was falling from sky to earth but when I was going to crash to it, some one put me calmly on the earth and it was when I could feel I am in my bed and sleeping the nightmare was over.
