Why do we have nightmares?

Answer 1

It's your minds way lf dealing with something that's bothering you. Sometimes there are things you're nor facing but they need resolution. Write down a nightmare and look at each image in the dream. Look at what each thing separately means to YOU. What does it represent and how do you feel about it. Often the answers are right there if you look at them rationally in the light of day. Sometimes you need to wait until the emotional factor is less so give it some time before you examine it.

Answer 2

Nightmares most often occur when you sleep on your back. Your tonque falls into the back of the throat cutting off oxygen to the brain causing scary images to play in our heads. You can also have nightmares if you are abused in any way, if you watch a scary movie, go through something traumatic. There are so many different reasons.
