A nightmare

Last Saturday and Sunday, I dreamed badly at night. I'm sorry I can't tell you about the details but anyway, it was nightmare for me so I was very scared! When I got up, I sweat a little with fear.
From the topic, I will give you a question. That is "Did you dream a nightmare in these days?"
Please tell me about your dream. Of course, nice dream is OK!
By the way, do you have any ways when you have difficulty falling asleep? For example, you count sheep. "There is a one sheep. There are two sheep. There are........."
In my case, I listen to the relaxing music. Then, I become sleepy and I can sleep well. If you have some good ways to sleep, please tell me that! Thank you.
