Dreams often reflect subconcious desires or anxieties, but sometimes, to paraphrase Freud, a dream is just a dream.
In other words, don't try to make things harder for yourself. This lifestyle is complicated enough without addind worry about being found out. (Which is, by the way, my diagnosis.)
If you get caught in something, or found out, it is nobody's business but yours. I know you are a bit young to appreciate it, but it is really true, and most people will not even care.
