Decentering an be regarded as central change strategy which is a Mindfulness-Based Cognitive Therapy,
and it involves act of stepping outside of one's own mental events which then results to an objective as well as non-judging stance at oneself. As regards a document, It should be noted that decentering is the process through which a document is repeatedly translated from one language to another and back, each time by a different translator.
Foreshadowing is an advance sign or warning of what is to come in the future. It often gives a small hint as to a large plot twist or change that will happen. Hope this helps!
