Steeds in the Night

Oddly I had the longest "sleep" I have had for about one month last night but it was beset by not one, not two but three nightmares. Two of them ended with me trying to scream in the dream, which both woke me. That is something I have only done once before. I can't really remember most of what it was all about though. The most lucid bit was the seeing the moon in a clear sky, clear except for a crab-shaped cloud just below the moon, I scrambled for a camera, but couldn't find one, so I switched on the light and someone yelled at me, as it was too bright.
