If many of my most important and recurring dream signs have no occurence in waking life then how am I supposed to do a critical state test relating to them?

Here's one for example... I was raised in Long Beach California for most of my life and then moved to Tacoma Washington about a decade ago yet many of my dreams take place in Long Beach California. A place that I haven't been to (or lived in) for so many years. How would I go about performing a critical state test in such a situation? This is one of many recurring dream signs for me that have no place in waking reality and I know for a fact that it's going to happen again.
