Sleepwalker

A Sleepwalker is a role that causes the player to randomly visit another player in the night. A player does not know he is the Sleepwalker.

This is a negative utility role because the Sleepwalker may be wrongly suspected of being scum if he is seen visiting a player the same night that the player dies by some means or another (e.g. failed recruitment attempt), or the same night the player was under the protection of the doctor (which could be taken as a failed night kill attempt).
