IIN I'm 27 & still spooked of the dark and don't leave closet door ope

If you're 27 and scared of the dark and monsters (not being direct, MONSTERS), I wouldn't say that's normal, it isn't. Normally, from what I've experienced, you aren't supposed to be scared of the dark by the time you're 9, maybe even 7... Most 7 year olds I've met are scared of the dark. I'm getting off subject. Anyways, if you're 27 and scared of the dark I would recommend doing the opposite of keeping yourself "safe" from the freaky monsters in your closet, for example, put your leg over the side of the bed and wait. Nothing will happen. When I was scared of the dark I had that problem. I put my leg over the side of my bed and waited until I passed out, my leg was still there when I woke up and I was alive, lol. Trust me, do the opposite, scary or not.
