Lyric discussion by Shoshin08 

Cover art for Night Comes In lyrics by Richard & Linda Thompson

This song indeed probably is associated with his Sufi interest of the time. At some he even joint a Sufi communian for a while, it's said. The dance probably is the wirling Sufi dance, and his new friends are found in his new faith, altough i agree with the other comment the additional lyrics give some of it a twist:

Well. I may find That street tomorrow Leave the shadow Of my lonely room

See my one My one and only Heart and soul I'm coming soon

This assumes his lust for real companionship is only a vision, ideal, dream or experience in his mind, not something aquired in reality yet...
