I get both types you've described. I regressed to a child for a week at a time once, and occasionally I do the same thing now.. I tend to go to bed and clutch my stuffed toy and won't go anywhere without him.. which is odd for a 24 year old, but at times I need that comfort like a child.

I also just drift away and feel nothing, phsyically or emotionally and sort of go 'offline' as I call it. Sometimes I'll even start dribbling (ew) and my husband says my breathing goes shallow and he has to remind me to breathe.. i just stop EVERYTHING.

I don't think theres any such thing as a normal type of dissociation- it's complicated and multi-faceted
