The dream in which you see nails, means that you should extract the daily bread by a hard work. If in a dream you hammer nails, in real life you will not aspire to reach a high social status. You consider that enough to be the honest noble person. To trade in a dream by nails means that you will have an interesting work which, however, will not bring you the expected income. To dream about bent and rusty nails - to diseases and failures.
