So I am in the dream, when I notice I have this nail in my hand. As I go through the dream, this alien starts chasing after me for the nail. I don't know why but I keep it from the alien. He chases me around town, some times he manages to get the nail, but I manage to get it back.
After awhile I start being creative about how I keep the nail from the alien, one time I hid it among other nails in my hand, other times I dropped the nail just before the alien searches me for it.

Most of the dream is hazy and forgotten, so sorry if none of this makes sense, I know it doesn't make sense to me.
