If you thought that your subconscious couldn't create something so horrific, then you haven't played any Silent Hill games or taken psychedelics. I tell ya, I saw some pretty disturbing images when I tried LSD, but they didn't linger and were replaced by pleasant ones; but I'm fairly morbid anyhow. I've had some vivid nightmares that scarred me like none other, but not ones with sexual intercourse with a family member. Are you sure that it was your father? It may not have been; dreams are rather vague sometimes.
tha crazy thing about that is ive had almost tha same dream. it started that i was fuckin this guy that im crushin on, then all of a sudden i was having sex with my dad.
Good call on the Freudian thing. I think most of us have had that damn sicko dream. Try self analizing. We tend to make the best justifications of our dreams.
