Spontaneous imagination is defined as effortless, surprising and instantaneous. For example, you’re washing the dishes and suddenly have a great new idea for a drawing. It feels like your idea literally “came out of nowhere.”
Controlled imagination is defined as a process that is consciously initiated, guided and terminated. For example, you’re washing the dishes and consciously decide to think about how to resolve a conflict with your roommate. You intentionally stay on task, brainstorming ideas and refining until you have an answer, at which time you stop thinking about it.

In the comments section, Mados, Musings, and I (mostly Mados and Musings, I just contributed once and read the convo in fascination) ended up getting into a conversation about different modes of thought and types of imagination (which are heavily linked, I believe, thus this post covering both), which provided the inspiration for this post. I actually meant to get this done a week and a half ago, but… yeah.
