If you dream that you are in an accident at sea, you may be feeling disappointed in love or having problems with people you are close to.
If you are drowning in your dream, your emotions may be overwhelming you.
If you are trying to rescue other people from a shipwreck in your dream, think about what they mean to you or what they represent. It could be that you are trying to rescue or revive that part of you that this person represents? For example, if the person you were rescuing is considered confident by you in waking life, it could be that you are trying to retrieve your own confidence?
Also note that ships are a mode of transport, so in dream they represent your journey through life.
Also, as they travel on water, which itself reflects your spirituality, a ship represents your spiritual journey through life.
So, bearing this in mind, a shipwreck in a dream could indicate you are not on the correct spiritual path, or that you are worried your spiritual growth is in danger because of current events in your life.
If you were not involved in the shipwreck but instead were diving down to explore the wreck in your dreams, it may be that you are trying to search your hidden depths for spiritual treasures?
