How about "passionately obsessed"? LOL Thank goodness DH is an enabler and sees nothing wrong with it!
DH watches a lot more TV than I do - sometimes I'll come into the room and he'll say, "Oh, I wanted to show you this..." and he'll pull up a show he'd watched and saved just so he can show me a quilt that was in a scene.

What a guy, right? LOL
I don't usually mentally quilt to fall asleep, I'm more likely to imagine more mechanical things, like tracing threading paths for various machines in my mind; or trying to envision every step of taking apart and reassembling a tension assembly on one of my old Singers. Designing quilts is too exciting and if I come up with a good idea I either have to write it down or I lay there and fret I'll forget it. But tracing thread paths or thinking about rebuilding tension assemblies is not exciting and requires enough focus to make my mind settle down and not dwell on other things.
I've dreamed about quilts and quilting too. Usually one or the other of my grandmothers show up in those dreams too - both were obsessed/avid quilters as well, so if I'm dreaming about quilts, one of my grandmothers usually can't resist making an appearance too! I'll always regret that both of them passed away when I was relatively young and years before I got into quilting for myself. I always wish they could have seen that and known their passion was being carried on in the family because nobody else on either side of the family has become a quilter. That's probably why I regularly insert them both into my quilting-related dreams.
