Ah yes, the Jack that we barely know about since he, technically doesn't have a backstory when he first became popular and was and still is, one of the mysterious creepypastas around. Well, let's see how we can escape him

1.) Know how to wake yourself up. If you're a heavy sleeper, this skill could be what saves your kidneys or your life. This is allow you to be able to get tf up when blue skinned Hannibal Lector here is trying to cut you open in your sleep.

2.) Have some sort of security, this is especially important for Eyeless Jack, as he doesn't leave any evidence of him being there other than you catching a glimpse of him out of the corner of your eye if your lucky, or unlucky. You can be the judge of that. Anyways, invest in some security cameras, or simply just have your pet sleep in your room. Trust me, they'll start cutting up the second thet feel as if something is wrong. Especially dogs and cats. If you can't do these things, then do some simple yet effective things like locking your door at night and locking the windows. Oh, and make sure you check your under the bed and in the closet. Just in case

3.) Honestly, I know I've been saying the opposite of this, but have some sort of religious symbol fam! Eyeless Jack has been (Somewhat) confirmed to be some sort of demon. So grab that holy book and smacketh him thy head with it!

4.) Make sure you look in the corners of your room, he's usually can be found chilling there when he's not trying to steal your kidneys in your sleep.
