Dream about swallow is an evidence for your sense of mortality. You need to rethink the choices that you are making in you life. You need to make-up with someone. The dream is a clue for the progress you have made. You are acknowledging the authoritarian within yourself.
Swallow dream is sometimes your flighty thoughts and frivolous ideas. You are less than proud of yourself with something that you did. You need to get rid of something in your life. The dream is a portent for your intimate self or childhood self. You are trying to escape from some current situation.
If you dreamt about swallow:
Hold your tongue when talking with others. People you communicate with are likely to have a very conservative point of view. Don’t scare them away with any wild and crazy ideas. Don’t reveal too much information all at once. Use tact at all times.
