In this dream, the snake probably represents a problem that the dreamer fears will affect the son in some way. The dog represents protection, and is the first solution tried in the dream; "can I protect my son?" The sock might represent hiding (ignoring) the problem or it might be a play on words: "can I sock this person who is troubling my son?" When the son is playing with the snake, the dream is considering whether the problem is really as dangerous as feared. This type of dream allows the dreamer to experiment with various ways of approaching a problem while in the security of sleep.
See a psychologist.
The snake probably dies soon.
