Hope you're still alive.

Definitely stock up on whatever seems to be working against the creature hunting you. Maybe find something you can put on yourself to hide your scent. Also consider it's possible that the monster will change from night to night, so stay alert.

It seems from what you described that others cannot see you or the monster when the hunt begins. With that in mind, you should prepare to be all on your own for the next 2 nights.

The creature is clearly nocturnal, so you could try shining a light in its eyes if you're being chased to stun it. Alternatively, you could pour something onto its eyes, like paint or some other thick substance. As well, it seems to have a keen sense of smell. Maybe having it near a rancid scent will disorient it, which would allow you to run if necessary.
