i have experienced both, not necessarily consistent every single day though.

for me, i have forgotten memories, things i 'feel' yet have no memory for, beginnings and ends with no in between of the actual trauma, things i was told i was witness to with zero memory (years after i was told repeatedly my childhood wasn't 'that' bad but was finally admitted to by my mother).

i also have chunks of time that are 'missing.' i have never done well with timelines because i do not know what year things happened or always even what age i was. i look at pictures and can't base timelines that well (maybe because my hairstyle changed so much lol)....but have lost several years combined due to the chunks of time i have lost...but i also have just blurry chunks of time lost.....well, eventually i guess it ends up being completely lost....i tend to remember a tiny bit while dissociated and then once the dissociation lessens (depending on how severe it is and what type), it becomes fuzzy for me but then days or weeks later, i am not able to remember it.

can you have missing time without actually switching to an alter? because for me, i don't think i have ever had one fully take over, at least not very often. i've always been blended with one or a few but haven't always known it either (easier to figure out as i've gotten older though, just not which one anymore).

i have the 'normal' type too with time passing while watching tv. being tired can cause that type for me.

i have justified the above not 'normal' time loss just because nothing odd or unusual ever occurs, so i tend to think it doesn't mean the same or matter as much or something.......i also don't do things in my life, so it doesn't affect me except going through it and the after effects mentally and physically of it. it takes a real toll on my body/mind, etc. and can be incredibly distressing for me.

i lost two or three straight months due to severe grief and dissociation early this year. that was really scary. i can understand why it happened, to be protected, but i'm not sure i ever lost that much time before....it tended to generally be here and there for a few hours a day or sometimes a few days at a time up to a few weeks of fuzzy headedness.
