"My name is Aaron Hostle, I woke up in my own house. Recently I've been having nightmares so lifelike that I can't explain them. My doctor just tells me I'm imagining things and gives me these... Medications. He gave me sleeping pills aswell, but why would he do that when I say countless of times that I'm afraid of sleep? I've started to figure out a reason to why I'm having these nightmares every night, since it's the same one all the time. It can't be normal. I can't tell the difference from reality and dreaming. I don't even know if I'm awake now... Am I going insane?"
