Also this one, not really horror but has that creepyness to it https://www.mangago.zone/read-manga/stigmata_aikon/

I was actually hoping that he would have a human/humanoid form so I continued reading it until the end.
any horror bl recs like the summer hikaru died. preferably manga but manhwa is good too
