Sleep research shows you are not alone. In one study, thirty-eight good sleepers were instructed to go to sleep as quickly as possible. Some of them were told that after the nap they would be giving a speech. Most people really do not like to give speeches. Indeed, this group had far more trouble falling asleep and slept less well when they did. Other data on insomniacs show that they are more likely to be worriers. Put simply, it is hard to sleep well when you have things on your mind.
