Help me find this I read it years ago but I cannot remember the name. There are these two guys on a road trip or something and one is in live with the other I can’t remember if it was one sided or not but they get caught in a snow storm so they stop at this hotel. Once in the hotel one of the guys splits into multiple versions of himself. Like his anger become one person his negative thoughts become one person exc. If I remember each personality starts to get killed off while they are trapped in this hotel . That’s about as much as I remember (also I’m pretty sure the hotel keeper had a rose for a head)
