Nightscape, dayscape...

I'm starting to have bad dreams all the time again. I always have them some of the time, but now I'm starting to have them all of the time. 'Bad' has also gone to 'worse', the last few nights.

Additionally, I'm probing at something - that's actually on paper - which may evolve into a tattoo design in the near future.

PS: Question

Have any of you got experience keeping a regular dream journal? Either public or private, computerized or written longhand...

If so, how do you keep it? Do you write down all the dreams you have, or just ones that seem particularly vivid or interesting? Does it help you remember dreams better when you wake up, with practice? Does it help you have more control over your dreamscape?

I figure, everything - every stimulus, pleasant or otherwise - is some kind of resource. I might as well start trying to make use of more of them.
