We think this sounds delicious, especially since Beat will not have any certainty that it actually happened to him! Go ahead and weave in some unsettling nightmares from a past life any way you see fit and make him reel. Feel free to get creative over what sets Beat off for this. Maybe a Fog follower or priest says something that sparks a nerve, or he gets riled up in all the wrong ways during a future event. Strong emotions are powerful, aren’t they? However it happens is up to you.
