This dream may symbolize your inner fears and insecurities that are manifesting in your waking life. The road trip with two unfamiliar girls who are your best friends could represent your desire for new experiences and connections, but also your fear of the unknown and unfamiliar. The hotel room could symbolize a temporary resting place or a state of transition in your life. The fact that you stayed behind while the girls went out to a bar could suggest a sense of isolation or feeling left out. The cockroach, a common symbol of fear and disgust, may represent a specific fear or anxiety that you are trying to avoid or ignore. However, the fact that it grows in size and hisses at you when you try to confront it could indicate that this fear is becoming too big to ignore and is demanding your attention. This dream may be urging you to face your fears and insecurities head on, rather than avoiding or suppressing them. It may also be a reminder to reach out to your friends for support and guidance in navigating these challenges. Overall, this dream may be a reflection of your inner struggles and a call to address them in order to move forward in your personal growth and development.
