I could say you wake up one morning after a long night of drinking and you find yourself in a winery. I could say you wake up one morning after having a major concussion and find yourself in a winery. I could also say you are in a dream and you're in a winery. Are any of these statements true? Possibly, but the only way you're ever going to find any answers is if you continue to play through the game series. (Or just wait until they're all released and read the story online. - But where's the fun in that?)
