4 And pillow was my helmet fair displayed;
displayed > spread out (presumably his head was resting on the "bunch of haires" mentioned at 107.32:2, and "helmet" should thus be read as "helm" or "crest"; but cf. 304.53:9)
5 While every sense the humour sweet embayed,
humour > dew [of sleep: cf. 101.36:2] embayed > bathed
6 And, slumbering soft, my heart did steal away; 7 Me seemed by my side a royal maid
Me seemed > [It seemed to me that]
8 Her dainty limbs full softly down did lay:
dainty > delightful, comely full > very, exceedingly
9 So fair a creature yet saw never sunny day.
