Being rescued in dreams is a powerful image, since it leaves us indebted to our rescuer. Rescuing someone else, particularly someone known to us, often suggests that we wish to have a, or form a different type of, relationship with that person.

If we do not know them, then the character may represent part of our own personality that we need to pay attention to.

The knight rescuing the maiden signifies the idea of the untouched feminine being rescued from her own passion.
