The Thorns
Scholars have said that whoever sees himself running on thorns, it may indicate his procrastination in paying debts. Whoever is harmed by thorns may incur disliked debt commensurate with the harm. Every thorny tree symbolizes a difficult man, proportionate to its thorns.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
