Drowning dreams are usually closely connected with things, situations, emotions which overwhelm you in the waking life. You feel you can no longer control your emotions or certain situations in your life and you feel like drowning. Taking into account the fact that water is the main symbol for human subconscious, to drown as dream image is related to all negative emotions and energy accumulated in this inner layer of your self.
If you dream that you are drowning but you eventually manage to survive the accident, this means that you will manage to put things in order and find a way to hinder those uncontrollable primitive desires and emotions in the real life, too. If you drown, this means that you are going to put an end to the unpleasant and uncomfortable situation you find yourself into and start it all over again. Therefore, drowning to death in a dream does not bear a negative significance, as it stands for a new beginning in your waking life and for an emotional re-birth.
If someone else tries to drown you, this is a warning that you should pay attention to close people in your waking life, as some of them may not be trustworthy, but planning treachery and betrayal behind your back.
If you see someone else drowning in your dream, this may also speak about your situation, as other individuals in dreams are usually aspects of your own self. Another possible interpretation to this dream image relates to the fact that you may become too involved with someone in your waking life. Or you may be overprotective or possessive with someone in your waking life. Try to get more in control of things happening in your life and also try to control your feelings and emotions so that they do not hurt yourself or people around you.
If you rescue someone from drowning in your dream, this is a good dream omen and means that you will manage to refrain from being too possessive and 'asphyxiating' those around you. Accordingly, if you are rescued by someone else from drowning this means that people around you will stop being overprotective and possessive with you and will give you the freedom you crave for.
