Sewer – For sewer, see Sewage. The sewer in particular is a dark and dank place that is both scary and interesting. The problem with the sewer being interesting is simply that it always ends the same: someone gets covered in fecal matter. If you dream about going into a sewer it means that you have entered into some part of your life that your subconscious has determined to be full of danger and putrefaction. Enter with caution and if at all possible exit before you get started on this path in your life.
