I've had an ex that was a nightmare.... does that count?
The only time I had nightmares as an adult was right after 9/11. They stopped after a few weeks, though. I would wake up terrified, so I understand how upsetting they can be.
Check out this forum.... maybe someone there can help you figure it out.
