the dreams relate to the fulfillment of our subconscious wishes

In the early 1900s,Sigmund Freud proposed that while all
of our dreams, including our nightmares,are a collection of images
from our daily conscious lives,they also have symbolic meanings,
which relate to the fulfillment of our subconscious wishes.
Freud theorized that everything we remember when we wake up from a dream is a symbolic representation of our unconscious primitive thoughts,urges, and desires.Freud believed that by analyzing those remembered elements,the unconscious content would be revealed to our conscious mind,and psychological issues stemming from its repression could be addressed and resolved.
