Rain Parade - Talking in My Sleep lyrics

I know, I'm talking in my sleep Sleeping in my dreams Dreaming on my feet I don't know what it means There's something in my head But it don't frighten me I heard a knocking at the door I crawled across the floor And tried to let you in But you were gone before I could turn a key And almost certainly I find that people leave their homes To find a place to go I've seen them on the street But I don't wanna stop I thought I couldn't speak And I wanted to go home
