I think anybody who has ever had at least a couple insomniac nights straight knows these feelings exactly.
I don't think it has to mean exactly that the speaker is being kept awake by any particular trouble, even though it might as well be, but that being unable to sleep for whatever reason is enough a problem (and boy, it is), thus all the allusions to anything that ISN'T being awake (warm lullabies, coma, sunken sleep).
I also feel the "I'm dreaming" verse could go both ways, meaning as much that the dreaming (as in asleep) is what the speaker wishes the most, so much it's said in the present tense; but also that that's what the waking reality has become (a final loss of sanity).
