Dreadhalls and Alien Isolation VR Mod are the joint two scariest VR games out there so please take care to play them either wearing a nappy or have clean underwear handy to change into lol :D
If you don't have a PC powerful enough to play Rift games then there are several games here in the Horror and Mystery section of the Quest Store. Some of these (Dreadhalls, Drop Dead, Face Your Fears II and Affected The Manor) are all cross-buy - so if you buy them from the Quest Store you can also download and play the same title from the Rift Store for free.
