Seeing thorns in your dream signifies that you may encounter a difficult or uncomfortable situation in your life. It could also symbolize a person who is particularly challenging or bothersome to you. Dreaming of thorns may represent the burden of debt, falling into temptation, or moral decay. If you have this type of dream, it may indicate issues in your life that are prompting you to reflect and think deeply.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Thorns" (page 434).
In a dream, thorns represent a harsh, difficult, repulsive and a distressful person. Thorns in a dream also represent indebtedness, signing a loan, temptation, degeneration of moral standards, or social unrest. If a thorn pierces someone in a dream, it means that he will be tried with temptations, or that he will be hurt from something he hates. Walking on thorns in a dream means delaying or postponing payment of one's debts upon maturity. Thorns in a dream also represent ignorant and evildoing people who uphold respect for nothing, and who have won neither material nor spiritual success in their lives. Thorns in a dream also represent pain and sufferings, complexity of matters, sorrows, distress, difficulties, love, injustice, or harm caused by women.
