Strangling yourself can be symbolic of an unsuccessful attempt to take control or move into a position of power, 2 Sam. 17:23.
If you are strangling someone else it can symbolize a hatred for that person.
If you are being strangled it can be a demonic dream.
If you are watching someone being strangled it can be a warning about a physical or spiritual attack on that person
(Hanging) If one strangles himself with his own hands, or if he hangs himself with a rope which he attaches to the ceiling in a dream, it means that he is sufferings from depression, distress, or sorrow. It also could mean that he will not reside in his present house, or in the place where he saw himself strangled.
The same interpretation goes for seeing oneself suffering from asphyxia. (Also see Suffocation)
Something is denying you the air to breathe; something has got you by the throat. “Spit out whatever is sticking in your throat,” which means look at what is bothering you and get rid of it. Don’t panic about this dream.
The dream is giving you a chance to see what is holding you back!
