Dreams involving someone you like can often reflect your feelings and desires towards them. The act of the girl touching your chin with a feather duster may symbolize a gentle encouragement or a desire for connection. The feather duster could represent a light-hearted or playful approach to intimacy, suggesting that you may be looking for a way to express your feelings in a fun or non-threatening manner.

The lifting of your head to look at her indicates a desire for attention or acknowledgment from her. It could also signify your willingness to be vulnerable and open up to her in some way. This dream might suggest that you are ready to take a step forward in your relationship or that you are hoping for her to notice you more.

Consider how you felt during the dream. If you felt happy and excited, it may reflect your positive feelings about her. If you felt anxious or uncomfortable, it might indicate some underlying fears or insecurities about pursuing a relationship.

Overall, this dream seems to encourage you to embrace your feelings and perhaps find a way to express them to the girl you like.
