In the dream the artery was a hallway

I'm guiding the wire and the vessel keeps widening until I'm standing in a hospital corridor that has no doors, only curtained bays with the same family in each one, all holding the same bouquet, all listening to the same song I can't quite place. The music keeps deciding what it wants to be and the rhythm is my pulse, only slower. I wake up with my hand still flat on the table like I was checking for a heartbeat underneath it.
