The meaning of Lion / lioness in dream | Dream interpretation
Generally a positive symbol that suggests physical strength and success in waking life. It can also suggest self-assertion or the need for it to be expressed in waking life because of the lion’s roar. If, however, the lion is small or injured or in a vulnerable situation, this could suggest that the dreamer feels he or she is in a dangerous place, but also that these difficulties can be overcome with strength and daring.
If a lion is chasing you, this is most likely due to a struggle with natural feelings of anger or aggression.
