text: what does a black cat means in a dream? in the dream he was atacking me. and i was on the other side of a door. everytime i try to get out through the door, he would try to attack me. cat is self willed, not trainable it can also mean unclean spirit, deception or witchcraft. black means lack, sin, grief or evil. look at the other circumstances in the dream and how you felt when you dreamed it to determine which meaning is appropriate.
