Dreaming of the head symbolizes thought, wisdom, reason, intelligence, trouble and dignity. Because the head is the most important part of the human body, it controls the whole body and life. And because the head is the closest place to worry in all parts of the human body, it usually means sadness.
The performance of that head struggling from time to time shows that you have been a little annoyed recently, being troubled by some small things, or friends around you being troubled by some small things, which has a little influence on you.
