Why some people have dream and other don't? Why do we have nightmares?

Question

Some people have nightmares when they have bad experince in their life, by the recent trauma and when people see terror.

Answer 1

You shouldnot be having nightmares. When you lay down at night read a few scriptures from the Bible and Pray and you will see, the nightmares will go away, Start reading a chapter of the book of Psalms at night before bedtime. Nightmares will torment you if you let them but you can make them stop. If you go to church ask your Pastor about them. Good luck and I pray that no one has anymore nightmares!!!

Answer 2

everybody dreams every night, it happens when you are in the r.e.m. stage of sleep which occurs a few times a night, however you only remember your dreams if you wake up in r.e.m. e.g by an alarm or sudden noise
if you wake up naturally you won't remember your dreams.
