Dreaming is normal. Don't let it affect your life. And dreaming is an anti-dream, that is to say, dreaming of bad things requires good things in reality.
The so-called dream is that the usual wishes or fears appear unchecked during sleep. Freud, an Austrian psychiatrist and founder of psychoanalysis, pointed out: "Dreams are things that the repressed subconscious mind rises to consciousness."
You said you often lose your hair. "This dream is probably because you are often dissatisfied with your hair."
Actually, it's nothing serious. When the psychological burden is cleared, it will be fine naturally.
