I am not a strong proponent of the dream analysis. So if we consider dreams to be a mere static of our brain trying to find a pattern in random thoughts or as a result of processing new experiences, how can reoccurring dreams fit into that theory.
I have dreams that over a period of more then 10 years have reoccured several times identical every time they happen. These dreams do not portray a place or persons i know in real life.
Also since my personal life changed over the course of these years one would assume there shouldn't be a trigger for these dreams to reoccur.
