Being stabbed in a dream by a wooden thorn means that the dreamer needs to overcome many small difficulties. If blood comes from being stabbed, then the dreamer should check the cause of the injury in life.
If the dreamer is a woman, the dream may mean sex, or indicate her fear of sex.
Dreaming of being stabbed by a wooden thorn symbolizes physical pain. In connection with general health conditions, dreams may also indicate vulnerability to infection.
For Christians, dreaming of thorns means that the dreamer is seeking spiritual help. The crown of Jesus symbolizes the suffering of faith.
