I, like Karen, rarely have nightmares. I usually can control my dreams but sometimes I just let go and see where the dream world takes me.

For anyone who can't fall asleep, I learned a technique years ago that may be of some help to you: After taking several deep breaths w/your eyes closed, visualize a chalk board and write the number 100 on it. Draw a circle around it and draw a slanted line through it. Then erase the whole thing. Then write the number 99 on the chalk board, draw a circle around it and draw a slanted line through it and erase it all again. Then write the number 98 on the chalk board and repeat the process. I rarely make it to the number 90 before I'm fast asleep. It tires the mind and allows it to give in and relax. Sleep has never been my friend. I can't "go to sleep"; I have to wait for it to come to me and this works. Give it a whirl.
