The Ocean House was... a little scary. But not really. Damn cool, though, you're right.
Actually, I don't know if I've ever told this story, but what freaked me out about that level wasn't anything in the level itself, but a hardcore deja vu thing I had while playing it. Now, I get deja vu really "bad" sometimes. I don't believe in psychics or anything like that, but I frequently get very specific feelings of deja vu over very specific things that I can prove I've never done before. Like when at work, we got these paintings in to decorate the basement, and I was writing out a card in our filing system while my boss was talking to the guys carrying the paintings and setting them up. I had this hardcore memory of which painting they were carrying, what she said, and what I was writing down. And it all sort of happened seconds after I had the "recollection". Again, I don't believe in funny business, but for some reason this happens to me a lot. I guess my brain just thinks it knows things it doesn't sometimes.
Anyway, that happened to me the first time I played the Ocean House level. I obviously had never played it before since I'd just bought it and hadn't downloaded it or anything, or even played a demo. But the beginning portion of that level started to feel really familiar, and it all came to a head as I went down into that one area where you find the journal. The journal is a little cheesy, but it was really fucking eerie because I felt like I knew exactly what was coming next as I read it, all the way up until the end. It's probable that I just guessed it, as it was pretty by the numbers... but it freaked me the fuck out. So when all the pots and pans and shit started flying, I got really weirded out and had to turn the game off for a while, haha.
