I came up with a theory about GTA V. So you remember when Trevor goes home after the game is finished and finds his mother in his trailer. But then you get the drugs from the van and when you get back she is gone. If Trevor's mother really wanted the drugs she would've stayed, and why wouldn't Ron tell Trevor there was a person in his trailer, maybe it was in Trevor's mind because he wants his mother back but he can't get her back so he imagines she is with him.
Then next, Michael joinging a cult. No other character can join the epsilon but Michael, and the cult tells him to avoid family, and sleep with more than 8 women a week, if you listen to the dialogue during the game Michael's wife (Amanda) says, "No more sleeping with random women" proving he might or might not be in the cult before you apparently do the quiz and meet people at the red truck and donate the money. Or maybe it's the aliens.
So next, "The Talking Dog" It leads Franklin to Dom, and when Dom is about to commit suicide, the dog leads Franklin to him. But the dog is only seen by Franklin and when he tells Dom about "his" dog. Dom asks about what dog and the dog is disappeared, clearly saying Franklin sees this dog, that might be possessed by aliens due to it talking to him, possibly through mind control.
Tell me what you think about my theory thanks!
