Nightmare

To me a nightmare is a bad dream that causes fear. Sometimes my dream contains danger. If it is a stressful dream I usually have trouble returning to sleep. As a child sometimes this feeling lasted for a long period of time. I don't have a nighmare very often, but when I do it takes me a long time to trust willing going to sleep. I would rather stay awake and look into the dark to make sure nothing bad is going to happen.
