Me and a few of my friends were fighting these bad people at a hospital and each of us had cool weapons. We were fighting when all of a sudden the Watterson family from The Amazing World of Gumball showed up and rescued my friends and I, but Darwin was covered in concrete in a box.
The dream may reflect your desire to fight against situations in your waking life that you perceive as "bad" or harmful. Your cool weapons represent the tools or abilities that you possess in order to deal with such situations. The appearance of the Watterson family can be interpreted as a symbol of help and support from unexpected sources. The fact that Darwin was trapped in a concrete box may represent an aspect of yourself that feels stuck or trapped in a difficult situation. This dream may be encouraging you to seek outside help in order to break free from this state of being immobilized.
