For me, seeing a giant in a dream may mean that I'm dreaming.
Non-lucid giants could represent that feeling that you are over your head with stuff.
1. Do you feel like you are still not good terms with someone?
2. Do you feel like you don't measure up to something or someone?
3. Why do you think you felt the need to find a better sword in the dream?
4. Are you under any stress?
Perhaps an obsession with something is getting in a way of resolving issues with life?
This dream also could not mean anything. How did you feel before went to bed?
