Dreams involving insects, especially ones that become larger or more complex as you try to deal with them, can often symbolize feelings of anxiety or stress in your waking life. The bug getting stuck in your finger may represent a problem or worry that feels minor at first but becomes increasingly overwhelming as you confront it.
The dragonfly and wasp characteristics might suggest that this issue is multifaceted—perhaps it involves aspects of creativity (dragonfly) and aggression or fear (wasp). Your struggle to remove the bug could symbolize your efforts to confront or resolve this problem, but the growing size may reflect how it feels like the issue is expanding beyond your control.
Consider what areas of your life might be causing you stress or anxiety. Are there worries that seem small but are escalating? Reflecting on these feelings and addressing them directly may help you regain a sense of control. It might also be beneficial to talk to someone about these feelings, as sharing can often alleviate some of the weight.
