I dreamed that a woman gave me pink begonia flower: begonia flower, which generally symbolizes beauty, happiness and gentleness. Flowers in dreams also symbolize love. Pink usually represents love and romance. Women dream that sending flowers is probably related to love, which may indicate that your attention to love has increased. Your opinion of begonia is the key to dream interpretation.
As for dreaming of begonia flowers, we can't see them: we receive much more information every day than we perceive. However, when the brain center processes information, it will "discard" the unimportant contents in the subconscious, while the important contents are reflected in conscious activities. When sleeping at night, when the brain sorts out information, these information that is "discarded" in the subconscious may appear in dreams. It's not like you haven't seen begonia. You may have seen them, but you didn't notice them.
