Put on dread sleeves with a snake head on the end Or put them over your face so you can look like you dont have a face maybe :/

Medusa! Just rubber band some plastic snakes to your dreads, maybe wrap a few of them in black or green thread. Just throw on a black dress and you're good to go!(I realize you're a dude, but the feminist in me says not to care. Break down those gender barriers!)

predator had dreadlocks, geico salesman or just a caveman, and if you can somehow get them to stand on end, you could be the slim jim guy

Viking, barbarian, pirate, Samson ( from the bible) Robin Hood, Norse or Celtic god or you could just dress up as anything. You don't have to use your dreads as a theme but if you wanted to you could be a dready lawyer, dready car salesman, dready fireman, dready evil dentist or what ever Those last were silly but you get the message, right?

Wow, this is a pretty old post lol. Interesting ideas though.

I tend to do the Viking things every year, but when you do it as a hobby it's just kind easy. I really plan to go as a human/predator hybrid one year.
