This dream seems to be rich in symbolism and may reflect various aspects of your emotional state and life situation. Here are some interpretations of the key elements:

1. Childhood Home: Being in your childhood house may represent a return to your roots or unresolved issues from your past. It could symbolize nostalgia or a need to revisit childhood memories and feelings.
2. Worms and Bugs: These often represent feelings of disgust or something that is bothering you on a deeper level. The worms, in particular, could symbolize guilt or anxiety about something you may have "brought" into your life, potentially relating to your past behaviors or decisions.
3. Sisters' Reactions: Your sisters' calmness amidst your panic could reflect your feelings about how others perceive your worries. They might represent aspects of yourself that are more carefree or unconcerned about the chaos around you.
4. Spiders and Snakes: Both creatures can symbolize feelings of fear or anxiety. Spiders may represent feeling trapped or manipulated, while snakes can symbolize transformation or fear of something hidden. Your reaction to them indicates that there may be underlying issues that you are struggling to confront.
5. Trash: The overflowing trash in your dad's room might symbolize emotional baggage or unresolved issues within your family dynamics. This can suggest a need to clean up or address these issues.
6. Jaguar: The jaguar may represent instincts or a powerful force in your life that you feel you need to control. Its transformation into a more dog-like creature suggests a desire for taming those instincts or fears, turning them into something more manageable.

Overall, this dream could indicate that you are feeling overwhelmed by certain issues in your life, particularly related to family and your past. It may be prompting you to confront these feelings instead of putting them off for later. The dream suggests a need for cleaning up emotional clutter and dealing with your fears and anxieties head-on. Consider reflecting on any unresolved conflicts or feelings you may have and think about how you can address them in your waking life.
