@oristarA,
"Play re-enactment" is something traumatised kids often do. It means that they continue to re-enact the traumatic event in their play.
Eg a child who has been in a car accident may have a toy car and dolls and repetitively re-create the events of the accident using their toys, or by some other means (like using a cardboard box to represent the car, with themselves and possibly soft toys within the box.)
Sexually or physically abused children may repeat the actions of the abuser on their toys or sometimes on other children.
Personally, I would refer to it as traumatic re-enactment.
It is thought of as being the childhood equivalent to the flashback...though some children can have flashbacks, too.
