Lama Ole’s answer:
If there is little emotion involved, then dreams are often only old, torn-off images from the store consciousness, which have little to do with you. Only if there is an emotional reaction involved—one feels good or bad—then the dream has meaning.
In dreams that feel important, the mind wants to tell itself something but it can’t really face up to it. So it encrypts the messages of the subconscious to the conscious. The subconscious plays hide and seek. It is worthwhile to look at this a bit because some parts of dreams do have meaning.
