It's probably nothing - don't worry! I had a dream my crush rode a horse into school and brought me to his castle. Does that mean he's a prince? Not really! I know dreams can have deeper meanings and sometimes tell the future, but this may mean nothing. You probably read or saw a movie or something that had a rapist in it and your dream was manipulated by this. As for the name... well, your brain can remember many things. Some things may slip back into memory sometimes. So don't worry. But still, be careful when you're on the streets. Don't be stupid and walk alone somewhere when its dark or when other people are not around. Just be smart always. :)
