Idea for home-brew divination spell.

I was thinking about divination earlier and thought about a fun idea for those warlocks who are contracted to some form of chaotic being. when they cast their spell to learn some information they are given what they ask for but the price is that they also are given some information that they "DID NOT!" want to know. (Example) Warlock: OH great being, help me find this person whom we need to complete this mission. Contractor: Yes my child they are in this location.... also they have imagined you in a full leather gimp suit on many occasions.
