lurkette chases bunnies in her sleep all night long. I've posted about it before (search "lurkette bunnies").
It's definitely Restless Leg Syndrome. I've seen videos of people with RLS, and it's exactly like what she does.
For a while, going on an Iron supplement helped a lot. The first couple weeks she was taking iron, it was totally gone. After a bit, it sort of came bac, but it's still better than it used to be.
I'm a really light sleeper too--she can pull the covers slightly and wake me up.
