I know that Freud in his "Interpretation of dreams" provides a number of examples of events influencing dreams several days to several months after the event has occurred. For example, a person sees a red bicycle in a shop and a week later may have a dream about riding/fixing/seeing the same type of red bicycle. Freud provides on example where an event took place months before the dream.
My question is - has there been any research that explained why there can be a long (4-7 days) delay between a real life event and a dream with elements from the event?
Just to clarify - these are not recurring dreams, but one time dreams about past experiences. Typically the delay between the event and the dream is several days.
