Yessss great song! Well, the name of the album in this case explains pretty much all the songs. Sleeping with ghosts, basically. The Special Needs refers to the physical relationship. What happens to it when the person isn't there anymore, but a "ghost" instead? all that is left is the memory and could that be strong enough to transform and materialize? it's actually what the videoclip explors. They have sex without being together, like materialized ghosts in the place where the other person is. Amazing.
