The story of Phasmophobia involves players taking on the role of paranormal investigators. They enter haunted locations to gather evidence of ghosts. Each location has its own spooky history and the ghosts within have different behaviors and abilities. The goal is to identify the type of ghost correctly using various equipment like EMF readers and thermometers.
Well, in another phasmophobia game story, a player entered an old, spooky house alone (which was a really brave but stupid move). He started exploring the rooms and found a Ouija board. When he used it, the room got freezing cold immediately. Then he heard a whisper saying his name, and he ran out of the house as fast as he could. He was so freaked out that he didn't go back in for weeks.
Sure. A group of players entered a haunted school in the game. They split up to search for evidence. One player went to the basement. As he was walking around, he heard a little girl's giggle. He thought it was just his teammates messing with him at first. But then he saw a small figure running past him. He chased after it, but it disappeared. When he turned around, the door he came through was locked. He was trapped in the basement with that ghostly presence and was terrified until his teammates found a way to unlock the door.
Yes, he has. Markiplier often does unique and entertaining segments, and this could be one of them. He likes to interact with different types of content related to his fan base, and reading fanfics, even the not - so - good ones, is a way to do that.
I don't think it's a true story. Such heist scenarios are often the creation of writers and storytellers to provide thrilling and adventurous experiences. There's no evidence to suggest it's based on reality.
His friends like Wade and Bob could be main characters. They would be the ones who first notice the change and try to help him. They might have some really funny reactions and also help him come to terms with being a girl. Maybe there could also be a mysterious character who caused the transformation in the first place and they have to find this person to reverse it.
