Like Sand Through Your Fingers: Dream Journaling

Have you ever had a dream and awoken with a feeling of urgency to tell someone anyone about it?
I personally have. As luck would have it I am a paper collector. If it's efemera I love it and I want it. I have a lot of paper in my house and I make sure some is next to my bed within reaching distance along with a writting implement. So a few times I have woken with the feeling that the dream was degrading so I reach out for my journal and the pen or pencil and wrote furiously in the pitch black of my room. I will write till I'm sleepy again and go back to sleep. What comes out in the morning is very enlightening. Does this happen to anyone else and if so how often?
