The Inverted Head
Scholars have said that if someone sees their head inverted in a dream, and they intend to travel, it might indicate an obstacle preventing their departure, and that they will not achieve their desires immediately but eventually. For a stranger who is traveling, this dream might indicate their return to their homeland after a delay and against their expectations. Sores or pain in the head and neck might suggest a general illness affecting people.
