The Stranger Ritual

DISCLAIMER: I do not recommend messing with the paranormal. I only post these games for entertainment and because we all love a good scare.

The Stranger Ritual is cast as a killing curse by summoning an entity known as the Stranger, using a doorway as a portal. Nothing is known of the Stranger, anyone who has seen it has gone blind or insane. It was found on the Creepypasta Wikia and I believe the User Sylar1610 to be the author.

~You will need~

• A room with a solid wooden door. It should not have any peepholes. It should have a locking system. 
• A photo. It cannot be an image of a family member. It must be recent and clicked by you. You should know this person’s name. 
• A black and a white candle. 
• A lighter.
• A piece of chalk.
• A gift. It must be an impersonal item, recently bought. The OP recommends candy. 

The Nesting Doll Game (Matryoshka Game)

DISCLAIMER: I do not recommend messing with the paranormal. I only post these games for entertainment and because we all love a good scare.

The Nesting Doll Game is a fortune telling ritual, penned on Reddit NoSleep by User kukla-ne-plach. The game involves using Matryoshka dolls to grant wishes or receive good fortune. I’ve added some tidbits sourced from the OP's comments to complete the instructions.

According to OP's story, this game was narrated at summer camp by a group of senior boys. In Russian it is called, "Udachnaya Matryoshka," meaning "Lucky Nesting Doll."

~You will need~

• A set of Matryoshka dolls. The OP recommends having a few sets on hand. They must be antique or the ones passed down as an heirloom. New ones are not as effective. 
• A room with a large mirror. It should contain one door and no windows.
• A few boxes of candles. The more, the better. 
• A lighter.
• A wastebasket
• Paper and pencil.
• A container of salt.
• A lucky charm or religious symbol tied by a thread. 
• A friend for assistance.
