Couple typos H: "alseep" and "woolf" (unless some covert modernist ref?) and I think it could do with some tightening up (for example, you could begin on the second line as we already get the sense of a dream. That said, some superb lines ("dub nodding on its thumbs" is just one) and like I say, it does get across the dream state very well. Cool.
