Boathouse

To see a boathouse in your dream indicates a feeling of confinement and staleness in waking life. Just as a boat sitting idle and unmoving in a boathouse, you feel in waking life that you are being stuck, not progressing nor growing.
Dreaming that you are preparing to take a boat out of the boathouse prominently implies that you are soon to be free with more choices in waking life, especially if you untie a boat and set it out into the open water in your dream.
