There's
a site with some really good ideas on how to write your own monologue.
You have to scroll down a little, but once you do, the ideas are
excellent. http://monologuesbyjanetstiger.com/Custo...
As for personification being part of it, personification is when human
traits are given to inanimate objects - like death came with a scythe
in hand.
Here is the definition-
Personification is giving human traits (qualities, feelings, action, or
characteristics) to non-living objects (things, colors, qualities, or
ideas).
For example: The window winked at me. The verb, wink, is a human action. A window is a non-living object.
If you have questions, ask the person giving the assignment.
