It is inconceivable that a person who wrote a book, say 20 years ago, would be able to interpret the meaning of symbols in people's dreams today.
I agree! I was never fan of this kind dream interpretation, even though I asked myself “how did they write these books on what bases?” Just like Jung explains “Thus, if the dreamer is being chased by a crazed killer, the dreamer may come eventually to recognize his own homicidal impulses.“ Does it mean that our dreams are part of our subconscious? At some point I think it is, but sometimes there are dreams such as nightmares that don’t make sense. At the end each dream depends on persons’s personality.
