DEAR DOCTOR K: Is there anything I can do to stop having terrible nightmares? They scare me, and ruin my sleep.
DEAR READER: There may be something you can do. The first thing you should know is that everyone has nightmares occasionally. That includes yours truly. Just as we don't really know why we sleep, we don't really understand nightmares. We also don't know why some people are more likely to have them.
