Emily – The disaster coming was the feelings you are trying to work out about your boyfriend. The dream paints an awful picture of you being left in the lurch by him – leaving you to drown.
That might be so, but dreams often are just showing what you feel is happening, but when you think about a lover, a friend or a person you know, you are only taking in your thoughts, impressions and feelings about them. So many people do not realise that they have an inner person equally as powerful as the external person you know. You have taken in millions of bits of memory, lessons learnt, life experiences along with all the feelings or problems met by meeting or living with them, and they change you and make you the person you are. The memories and experience we gather unconsciously change us and are not lost. It is part of you and is symbolised in dreams as a person or event. Such an inner person can appear in dreams because you still carry the memories or impressions of them, and so they influenced what you hold within you.
But your dream shows you ‘going under’ emotionally, which is bad news. If that is so you are caught in a bad position, largely because we are born as mammals, and mammals are prone to react with immense emotions when any threatening situation occurs. But as human mammals we are in an even worse situation, because wild mammals quickly lose their intense reaction, but as humans we hold on to it for ages because we think about it, which triggers the awful emotions again and again and again.
