If you see your own neck in your dream, it represents the connection between the mind and the body, or the mental and the physical. It is a symbol of self-control, self-restraint, and the necessity to exercise self-command over one’s emotions to keep them in check. Take, for example, the well-known expression “don’t put your neck out,” which is meant to serve as a caution against a certain circumstance.
A dream in which you experience an injury or pain in your neck suggests that there is a barrier separating your mind and heart. The way you feel and the thoughts that go through your head are not necessarily in sync with one another. You are experiencing a conflict of feelings.
The other interpretation of the dream is that it is a metaphor for something or someone that is a genuine ache in the neck.
If you have a dream in which your neck is big or bulging, it is a symbol of your short temper.
