Answer 1

lol you got issues (just kidding) I don't know why, but its nothing psychological.(not dangerous)

Answer 2

Interesting with the house on/in water. That's the second time I've heard that. As far as the skipping thing, it's probably something your subconscious views as really cool and likes to enact every now and then.
