It all depends. If you have a diagnosis of schizophrenia, it could be that you need a medication adjustment or to start writing down memories so to organize your thoughts. Or if you have Bipolar or Depression it could be a signal that something is off. Vivid dreams arise due to stress and not coping properly. While vivid dreams can also be your mind's way of figuring and sorting out your life for your sake, to better understand.
I have done some research on dreams, and used to keep a dream book and journal. If my dreams are off it's a sign that something needs to change.
