Chance Choice

When creating a collage, I pick up a handful of words cut from newspaper headlines, spread them on the table, and look for hidden messages, things my sub-conscious is trying to communicate to me. Today the words “chance” and “choice” asked to be paired.
Last night I dreamed I set free a group of dangerous creatures, including a hippopotamus-viper. A creature is something that is created. So in my collages, and in life, for that matter, how much is chance and how much is choice?
