i wonder why do people dream about certain things 

Not all dreaming is the same. It runs the gamut of human experience and sometimes beyond, incorporating a dizzying range of emotions and events, often with elements of the bizarre. Dreams can be funny, frightening, sad or strange.  Flying dreams can be exciting , chasing dreams can be terrifying, forgot-to-study-for-my-exam dreams can be stressful.

There are types of dreams classification  like nightmares, recurring dreams and lucid dreams. 

Here are some brief points on each of the dreams:

NIGHTMARE:

• is defined as frightening dreams that cause some awakening  people from sleep. 
• Nightmares can result from different triggers, including stress, emotional upheaval, and traumatic experiences. 
• They can occur as side effects of some medications, use and abuse of drugs and alcohol, and illness. 
• Nightmares themselves contribute to disrupted sleep not only by waking the sleeper, but also because they can lead to fear of falling asleep and returning to a disturbing dream. 

RECURRING DREAMS:

• are dreams that re-appear with some pattern of regularity. 
• Studies suggest that recurring dreams may contain more threatening content than regular dreams.
•  Research suggests links between recurring dreams and psychological distress
•  in both adults and children.

LUCID DREAMS :

• are an especially fascinating form of dream.
•  In lucid dreams, the dreamer is aware of the fact that he or she is dreaming, and often can manipulate or control the dream as it unfolds. 
• Research links lucid dreaming to unusually elevated levels of brain activity. 
• Studies have found that lucid dreamers displayed significantly higher
•  brain wave frequencies than non-lucid dreamers, as well as increased activity
•  in parts of the frontal lobe.
•  This area of the brain is deeply involved with conscious awareness, a sense of self, as well as language and memory. 
• Studies of lucid dreams are not only shedding light on the mechanics of dreaming, but also on the neural underpinnings of consciousness itself.
