My guess is that you are left with residual psychic sludge that was just "in the air" there. There were probably a lot of people there who didn't feel like they fit in, and didn't want to get undressed, but who did it anyway because they thought that they would then feel like they fit in. Likely lots of uncomfortable folks comparing themselves, hoping to be seen as "open-minded," and seeking approval. When people who flaunt that kind of stuff create an energy that leaves others around them feeling icky about themselves or the situation, it usually means that those people are more insecure and unsure of themselves than everyone else. I get the sense that before you were kind of immersed in that environment, you were perfectly fine with yourself. Shake it off, it isn't your stuff! If you're into smudging or some other way to get rid of toxic energy, I bet you'd feel a lot better. How about treating yourself to a nice herbal face mask, foot scrub, or bubble bath!
