Where and when do you write

I'm one of those people who is guilty of doing what you are not supposed to do as a writer. I don't write everyday. I write when I feel like it. Perhaps that will change in the future. I think right now I am not writing so much because of some health issues, but I would be curious to know how often other people write? Is there a place you feel more comfortable writing? Does it have to be that cabin in the woods, or can you do it while sitting on the toilet ha ha. When I write, I try to do at least three pages a day. That's actually good for me. I guess I'm more like James Joyce...he didn't write very much a day. Does anyone get ideas from dreams? I had a few of those. You know, wake up and write it down kind of thing. But they are few and far between. I seem to be inspired by just regular situations that I ask "what if" about, and sometimes I get a good idea. I hope whoever reads this might share their writing habits for all who visit this Blog. I think an exchange of ideas always makes us better writers!
