Cover art for Dressed In Black lyrics by Depeche Mode

Depeche Mode has had a long history of BDSM tinged songs i.e. Master and Servant, In Your Room, and others. Though somewhat more subtle than those previously mentioned, this song is about BDSM. Note the title "Dressed in Black", which refers to a black leather costume, the references to domination and submission of "I'm falling down again/ Down to the floor again" and "I lay here helplessly".

@Empiricalproof No, after a husband or other close family member would die in older days the women would wear a black dress in mourning, and would be left alone by all lovers until she stopped wearing black dresses. This song is about be led along and then being manipulated.
