In a sense, a literal sense in this case, werewolves can sort of see through time. Unlike visions the chemicals that causes smells can linger for months. It creates a maze of sensations that the werewolf must pick through with a nearly human brain. Some werewolves carefully hoard and store clothes of lost loved ones. On lonely nights they'll open chests and for a brief (if stale) moment it is as if that loved one was in the room with them again. Some of them says that makes the curse bearable, and others say that is the curse.
This was something you needed to know.
