Dreams involving giant creatures often symbolize overwhelming fears or feelings in your waking life. The giant black creature could represent a significant fear or anxiety that feels out of control. The fact that you were more scared for someone else than for yourself suggests that you might be feeling protective or concerned about someone in your life.
Being in the same place as the creature without being harmed may indicate that you have the strength or ability to face your fears, or it could suggest that you feel safe in certain situations despite the presence of fear. This dream might be urging you to address your concerns for others while also recognizing your own resilience.
Consider reflecting on any real-life situations where you feel protective of someone or where you are grappling with fear. It may be beneficial to communicate your concerns or take action to support those you care about.
