Since way back in those early days, I have never been bothered by nightmares. Of course, some nightmares are necessary and important for the mind to deal with things, so I do sometimes have them. But they are never over the top, freak out, experiences. Somehow, I am able to remain a step removed and know they are just bad dreams.
Conversely, I have good dreams, adventure dreams, ones that I can remember, almost every night. I am grateful for this and really enjoy sleeping not only for it's restorative powers but also for the free and tailor made entertainment provided.
