Thank you for sharing your dream. Let's break down the elements and themes present in it for interpretation.

1. The House: A house often represents the self or the mind in dream symbolism. The modern, open-concept nature of the house suggests feelings of openness or a desire for clarity in your life. The foliage surrounding it may symbolize growth and life, indicating a nurturing environment.
2. The Party: The celebration with many people, including familiar faces, could signify social dynamics in your life. It might reflect feelings of connection but also highlight a sense of alienation, especially given your limited interactions with most individuals present.
3. The Act of Violence: Smacking the woman from work signifies a sudden and perhaps unexpected outburst of aggression. This could reflect underlying frustrations or emotions that you may be suppressing in your waking life. The villainous smirk could indicate a struggle with feelings of guilt or shame about these emotions. The reaction from others in the dream reinforces a fear of judgment and consequences for your actions.
4. Teeth Falling Out: This is a common dream theme often associated with anxiety about self-image, loss of control, or fear of aging. Your panic in the dream suggests that you may be feeling insecure or worried about how others perceive you.
5. The Strange Creatures: The arthropod-like creatures with feathers or fur might represent aspects of yourself or your life that you find strange or unsettling. Their transformation and attack could symbolize inner turmoil or fears that are manifesting in your life. The fact that they don’t cause harm but still provoke panic indicates that these fears may be more about perception than reality.
6. The Relationship with Your Mom: Your mom’s presence without a visible face suggests a strong emotional connection or dependence on her support, yet it also implies a lack of clarity or communication in that relationship. Perhaps you're seeking her guidance or protection in dealing with your emotions.

Overall, this dream seems to reflect internal conflicts, fears, and perhaps a desire for connection amid feelings of isolation. It may be helpful to explore any underlying emotions or situations in your waking life that resonate with these themes. Consider addressing any feelings of frustration or anxiety and seek ways to communicate better with those around you, especially with family. Journaling or talking to someone you trust about these feelings could provide additional clarity and comfort.
