No, but the target you're supposed to be describing probably does.  (You're supposed to view the actual target, not the feedback picture, itself - more about that in later lessons.)  The idea is that, if you know what sense you're absolutely the most accurate at describing in regular remote viewing, then make a target pool that figures strongly to your best strength. For example, if you're most accurate at describing tastes, then the target pool should always have something in it with an identifiable taste. The only way to truly know what you are most accurate at describing in a remote viewing session is to keep records of your sessions and their results. Note I say "most accurate", not "favorite". Many people would rather view locations or events or sounds (music, noises, etc.), but are actually most accurate at their descriptions of some other factor at the site, such as the colors of things, sounds at the site, etc.. Keeping records of your work is what will tell you what you are most accurate at. Once you know that, you can devise (or have devised for you) a target pool that will insure you the most accuracy of session results because it always tasks you with targets that you're really accurate at viewing..
