I have the "I'm sitting in the back of the classroom naked" dream. The bell rings, and everyone heads out of the class without ever noticing me. What does that one mean?
I get ones like that where I went to school naked, and also sometimes in those I forget my locker combination, or I realize I forgot to take a class I needed to graduate.
Nudity symbolizes being caught off guard. Finding yourself naked at work or in a classroom, suggests that you are unprepared for a project at work or school. You may be uninformed in making a well-formed decision. With all eyes on you, you have this fear of having some deed brought to public attention. You fear that people will see through your true self and you will be exposed as a fraud or a phony.
Many times, when you realize that you are naked in your dream, no one else seems to notice. Everyone else in the dream is going about their business without giving a second look at your nakedness. This implies that your fears are unfounded; no one will notice except you. You may be magnifying the situation and making an issue of nothing. On the other hand, such dreams may mean your desire (or failure) to get noticed.
For a small percentage of you, dreaming that you are proud of your nakedness and show no embarrassment or shame, then it symbolizes your unrestricted freedom. You have nothing to hide and are proud of who you are. The dream is about a new sense of honesty, openness, and a carefree nature.
