Dreams involving friends and romantic feelings often reflect your subconscious thoughts and feelings about relationships in your waking life. In your dream, the scenario of buying a gift for Annie can symbolize the importance of friendship and the bonds you share with your friends.

Momo's confession that he likes you, along with the involvement of Brendon and Hailey, suggests that you may be processing your feelings about these friendships and the romantic interests within them. The fact that Momo is conflicted about his feelings could indicate your awareness of the complexities and potential tensions in your social circle, especially since you have feelings for Brendon.

Hailey's presence in the dream may represent a sense of competition or comparison among friends, which can often arise in situations of romantic interest. The stickers you were looking at with Hailey might symbolize the desire for fun, creativity, and light-heartedness in relationships, contrasting with the more serious matters of romantic feelings and potential conflicts.

Ultimately, this dream seems to be highlighting your feelings for Brendon, while also acknowledging the complicated dynamics with Momo and Hailey. It may be worth reflecting on how you feel about these relationships in your waking life and considering how to navigate them in a way that honors your feelings and maintains your friendships.

If you're comfortable, perhaps discussing your feelings openly with Brendon or Momo could help clarify the situation and ease any tensions.
