RPG Horror Game collecting (please read)

Ever since seeing the beauty of rpg horror games such as Ib, The Witch's house, Mad Father and Misao, I've started to turn into an rpg horror game collector. Though not all I have/want is true horror. There are also ones I want that aren't horror such as To The Moon. But I'm alot more interested in the horror ones, I don't know, they just feel more appealing to me for some reason. Anyways I was hoping if anyone can recommend me trying any horror games I possibly never heard of out. Also if so, I was wondering if you wouldn't mind linking me to where I can get it and how to get it to work. I'll show my list of what I have currently and the list of games I want to get soon. 
What I have is in order: 
Alice Mare 
Blank Dream 
Dear Red 
Dreaming Mary 
Go To Sleep 
Hello Charlotte EP.1

The Crooked Man 
The Sandman 
The Boogie man 
The dark side of Red Riding Hood

Now the list of what I don't have:
