Sword Options

There's a swordsman who challenges be to a duel. I didn't have a weapon so I'm in this temple rock garden. I pick up this rock which apparently is suppose to be forged into a sword. My dream skips how the sword was made, but what I get is this extremely flimpsy blade. To describe it, it was like it was thin like paper almost transparent, but could fold like cloth. When I start to wield it, the blade vibrated bluish and settled into a rigid form. This swordsman's sword was cut clean with one strike.

Thanks for the intepretations. I guess I don't read much into Freud. I kind of find it difficult to understand and believe that every pointy or sharp object has something to do with the penis or sex. On the other hand, this dream has given me ideas on constructing a sword out of nitinol wires, oddly.
