In Your Dream You Are Naked
From what I heard, if you dream you are naked and everyone else has clothes on this means that you are hiding some deep secret that will soon be exposed.
That might be true for some people.
I have a dream like this several times a month. I'm not always completely nude. Sometimes I dream I get to work and realize I forgot my pants and just have underwear on, or remembered pants but forgot my shirt. The funny thing is nobody seems to notice.
I think with me it's just more simply an issue of modesty. I'm not a prude wearing turtlenecks and stuff all the time, but I am very modest these days. I hate the thought of anyone even seeing my panty-lines.
