In general, something fragile means that it is easily broken. This can be interpreted as something that you would be worried about being broken or damaged. So if you are fragile in a dream, this could represent an aspect of your life that is easily broken and damaged, or an aspect of your personality that might be fragile to the point where you feel like it’s breaking down.
If someone is feeling fragile in a dream, this could represent the idea that someone has low self-esteem, or someone who may not have the best time what their life is going. It could also represent having depression and anxiety from feeling like no one cares about them. Or it could represent someone who is not assertive when it comes to their personal identity and who feels like they are barely holding on for dear life when it comes to their character or personality traits.
