Afterward I went to get some ice water from the dispenser in the fridge (another artifact of [ex]'s parents' house) and the scene changed to being on a spaceship, while still being the living room of my flat. (I have a fear of outer space which is often explored in dreams where I'm steering a spaceship or perhaps a planet; I think it is a metaphor for having no home, being lost, rootless) Maggie and Rebecca and some others of [ex]'s family were there and everyone was trying on Maggie's wedding dress, which was strapless, dark red (with a black zipper up the back), somehow both slinky and bodied, with a shirred waist, and looked amazing on EVERYONE (including some tall slender male person who might have been [ex] but I can't remember). I imagined it on me but didn't try it on, even though it was magic and fit everyone, because I didn't like the connotations of such an idea (and because I don't like strapless dresses). I stood off to the side, separate from the others and not interacting.
Then I was steering the spaceship by following the instructions of my ex (???) and manipulating a squishy ball, about the size of the exercise ball I sit on but translucent with mushy buttons and a jelly-filled representation of space inside. I followed the coordinates (just two numbers -- 24 and 22 I think), pushed the correct mushy buttons and looked inside at the right spot. I saw Earth and got freaked out, felt like I was falling, and woke up.
I'm not sure consciously what my psyche was figuring out, but I feel more whole after those dreams. The first two are extremely obvious but if you have an interpretation for the third I'd love to hear it.
