Is it Toggle about to harm Toggle? Should I be singing "The Science of Selling Yourself Short" while looking at this?
Lying in bed, taking a shower, doing mundane chores... these are all common moments for the good ol' brain to suddenly fart out an idea or two to keep itself entertained. Always a smart move to have a notepad or, in your case, ibispaintx close by to quickly jot it down before you forget about it. Nothing to be concerned about. Comedians and musicians also have these moments. It's how a creative mind works. Sure, "venting" can result in ideas (any strong emotion can), but don't worry too much if it just happens casually, as well. If you keep doing something, it becomes second nature... forming new ideas included.
