An island in a dream is usually a symbol of isolation.
You may dream of an island when you are feeling lonely and desire companionship and understanding. If you are shipwrecked on the island and hoping for someone to find you and rescue you, it can mean that you are trying to communicate with others but feel that you are not succeeding.
Alternatively, you may dream about an island when you are feeling overwhelmed by the demands of others. You are looking for a safe retreat where you can spend some time away from others, relaxing and restoring your strengths.
A dream of being on an island can be a message that you need to spend less time focusing on the external world and spend more time thinking about your inner self. Are there memories or emotional issues that you have been avoiding?
Dreaming that you are on a tropical island paradise can signify that you need a vacation – whether physical or mental – in real life.
