This dream is rich in symbolism and may reflect various aspects of your emotions, relationships, and current life situations. Here are some interpretations for the key elements in your dream:

1. Childhood House and Siblings: Being in your childhood home and the presence of your sisters suggests a connection to your past and familial relationships. It may indicate a longing for comfort or unresolved issues from your childhood.
2. Worms and Bugs: The pile of worms and bugs represents feelings of disgust or anxiety about something that feels overwhelming or dirty in your life. This could symbolize repressed emotions, unresolved conflicts, or aspects of yourself that you find undesirable. The fact that you brought them into the bed suggests that these feelings are closely tied to your personal space or sense of security.
3. Cleaning Up: Your stress about not knowing how to clean up the mess indicates a feeling of being overwhelmed by responsibilities or issues that need to be addressed. Covering the pile with a blanket may symbolize avoidance or denial about dealing with these feelings or situations.
4. Spiders and Snakes: Both spiders and snakes often symbolize fear and anxiety. Spiders can represent feeling trapped or tangled in a situation, while snakes may indicate deceit or transformation. The fact that your sisters are unconcerned about these creatures suggests a difference in how you and your family perceive or handle stress and challenges.
5. Spitting Up Worms: This image could signify a release of pent-up emotions or truths that you have been hiding from yourself or others. It might imply that you need to confront and express feelings you have been suppressing.
6. Jaguar and Trash: The appearance of the jaguar represents instincts, power, and the untamed aspects of your nature. The trash may symbolize things you wish to discard or get rid of in your life. The transformation of the jaguar into a more dog-like creature could reflect a desire to tame chaos or wildness in your life and integrate it in a more manageable way.

Overall, this dream may reflect feelings of anxiety or overwhelm regarding personal issues, especially those connected to your family or past. It might be helpful to take time to reflect on what aspects of your life need attention or cleaning up and how you can approach these issues in a healthier way. Consider discussing your feelings with trusted friends or family members to gain perspective and support.
