The only error I can see in this sentence is roll-a-coaster. I believe it should be a roller coaster instead, which is a ride in amusement parks. Other than that, it is more grammatically correct to say "I've just gotten off the wooden" rather than "I just got off the wooden" however, it's up to you.
The answer is "me". There are two valid uses for I and me. The former is used as a "doer" pronoun, such as in the sentence, <em>I took Sandra with me to the movies.</em> The latter is used as an object pronoun, which is applicable in the case of <em>Sandra went to the movies with David and me.</em>
Translated version:
I’m from Messaline. Sebastian was my father’s name, and my brother was named Sebastian too. He was dressed just like you are when he drowned. If ghosts can take on someone’s body and clothes, you must be a spirit who’s come to frighten us.
