I think dreads look okay if they are skinny, the super thick ones tend to overpower people. I have seen many people with dreads who are beautiful but the dreads were the only thing that you noticed.
I dated a guy with beautiful shoulder length hair and he chose to have dreads after a while. It looked okay on him, and he kept them washed, but it was not very pleasant to the touch, and made it hard to be close to his face without feeling scratchy or getting whapped by them if he turned his head too quickly. Plus, I missed the feel of his hair.
I think even if your style is different, it is not neccessary to go extreme in your hairstyle or clothing; your cool attitude and energy will come through even if you dress more "mainstream". I get the whole thing about the "energy" of the hair, but sometimes people miss out on who you are if they keep staring at the dreads.
