Have you ever had dreams tell you to wake up?

So, I was dreaming and in my dream I had to use the restroom. So in my dream, I went, then my dream continued, but I had to go again. So I went. Then my dream continued and darn it.. I still had to go.

Finally, I woke up and realized that my dream was telling me I really had to pee!

So I got up and went.

I'm wondering... do you ever have your dreams wake you up to go do something?
