TAPESTRIES!!! Maybe a beaded curtain to hang over your door. But tapestries are real nice. I have a beautiful pink and black tapestry with a celtic knot on it. It hangs completely on one of the walls. Since you don't have much wall space you can put it on your ceiling or even have it hang from the ceiling around the bed. I did that before and it's like you have a private little fort area if you're lying in bed. No one can see you.
I collect scarves and saris, sarongs. Any fabric with an intricate pattern, they're great to drape over trunks, hang from walls, line bookshelves. Check out fabric remainders at a craft/fabric store.
I don't know if it's already been suggested, but you can hang beads from your doorway. It's classic. Or, alternatively, a blanket. Get black lights as well. And black light posters. Do they still make those?! And you can get colorful blankets and scarves and stuff and drape them over everything. And get about twenty more lava lamps.
A great thing to do with tapestries if you don't have wall space is turn them into curtains. Just cut one in half and either sew the raw edge or use hem tape (basically a tape that allows you to just fold over the hem and iron it). You then just sew or use hem tape to create a bigger loop at the top where the curtain rod will go through. You can even use hemp rope as tie-backs.
