You take baths now but shower in the hospital but you were wearing your hospital pj's in the bath.

When I had "opposite" dreams like that, I was working on un-merging my mother (died when I was 3, was sick all my life, I don't consciously remember her) and stepmother. Until my t and I worked for 2+ years hard on that, I had nothing to refer to my mother as and could not refer to my stepmother as "stepmother," she was my "mom."

I remember one dream where I was trying on my mother's 1940 wedding gown (was my grandmother's before that, in 1911, hand made in Paris) and the second time, when I came for a fitting, it had been messed with and was wrecked or there was a different dress or something; there were two dresses/someone else had been there between me and trying it on the first time, I was trying it on twice, etc.

It reminds me a little of this dream of yours where you're mixing and matching different features, as if you have trouble getting them straight. My father married my stepmother when I was 5 and I was ready/wanted a mother and just glomped onto her only she wasn't a good match for me, was not my actual mother like I wished with my young child self. Even into therapy, I'd refer to that wedding as when "We" got married; not my father and stepmother. I can still remember too, when my father would come home from work and hug/kiss my stepmother hello, I'd worm in between them, with, "Me, too! Me, too!" obviously jealous/not wholly understanding the differences yet between my parents and myself as individuals.

Your brother knocked; would he actually have done that? (I have three brothers, the idea of privacy/a sibling knocking stretches the imagination? :-) What is the relationship between you and your brother? Various members of your family walking by and being concerned but not intervening in any way or being part of your experience, etc. like the bathroom was a "shell" around you, your skin, your experience with yourself versus your experience out in the world, etc.?
