Why do we have bad dreams and what do they mean?

We have dreams because they are needed to keep us mentally health. It is like the brain is watching films while we are sleeping because it has nothing else to do. Sleep deprivation leads soon to hallucinations and other problems! BUT dreams function is even to solve problems you had at the daytime. Haven´t you ever waken upin the middle of the night and suddenly remembered something or had a solution to a problem?

Maybe we forgot the Creator of heaven and earth..God the Almighty

@Bruce, maybe I was trying to say your subconcious mind is telling you you can do it and maybe that's why you dream about flying. Sorry if I got anything wrong

However you should know when it is not attributed to any of these circumstances, when it is just a warning for you or others in your life. Interpretation is usually the hardest part.

Thank you for sharing, Tina.

It is your subconscious reliving what you did during the day. If you have nightmares that could be from stress. Maybe there is a chemical in the brain that makes us dream. I do not know but taking psychology in school that is what we learned about where dreams/nightmares possibly come from.

It does'nt mean anything its only due to tension in your mind.
