When several alters are out at once, they may talk at the same time,
causing incredibly garbled sentences to emerge. Or they may listen at

understand what was said.
Additionally, switches may cause disorientation, even within multiples
that are co-conscious to some degree.
For multiple systems that are particularly integrated/co-conscious, it may

exacerbated with greater similarity between alters.
People who are dissociative but not multiple probably find themselves
