Those who have experienced night terrors will usuall C. have anxiety about going back to sleep after an incident. When you have a scary dream and wake up in the middle of a dark, black night, you aren't likely to be happy about closing your eyes once again for fear that this dream is going to repeat itself and scare you all over again. You are unlikely to have a restful sleep that night, you won't remember the dream vividly, and you won't use alarm clocks that often because that doesn't make any sense.
