For me it kind of depended what was going on in the present life, I think. When it became clear of the dx, but I was no longer acting out on those parts, if I can put it that way, then there was more waking up at the night time in the middle of conversations.
I take some steps now to settle everyone to sleep including holding a stuffie, using my CES device (if feeling rattled before I go to sleep), tucking myself in (sort of) and trying to meet the needs of other former parts that I think may be not settling.
I remembered when I first noticed this was happening and having mentioned it to my therapist. He didn't react to me in a strange way so I didn't react to me in a strange way either.

All the best.
