Being naked in your dream could mean that you need to be bolder in life rather than hiding away from others. Perhaps your subconscious is telling you to leave a fear or fears behind and move on because it's holding you back.
Perhaps you feel you aren't showing people the real you and you have been hiding the person you are for a long time. It might be the right moment to start being yourself and stop pretending so they can get to know you and not the version you've concocted.
If you felt uncomfortable about being naked in the dream then perhaps you are worried others will think you are foolish or not good enough to be with the people in your life or live the life you do.
If you felt self-conscious in a public space and people recognised you then you may be feeling uneasy about a situation in your waking life. Or that you are being rejected by someone close to you if they reacted negatively in the dreamscape to your body.
Embarrassment over being naked can indicate you want to avoid a social situation that's coming up soon. Consider the people in your dream- perhaps they are the ones who are due to be there.
Clothes are often about protection given that they can cover the parts of you that you're most insecure about. Without them- you may have felt vulnerable in the dream which can be a reflection of how you perceive things in real life. Do you see yourself as lacking protection or being out of your comfort zone? If so, this might be why you were exposed for everyone to see in your dream.
