Dreams like yours can often reflect feelings of confusion, fear, or a sense of being trapped in a situation in your waking life. The camping ground may symbolize a temporary state or a retreat, suggesting a desire for escape or a break from reality. The fact that your family wasn't your real-life family might indicate that you are exploring relationships or aspects of yourself that feel foreign or disconnected.

The woods represent the unknown or subconscious mind, where you may be facing unresolved issues or fears. Being guided by someone could suggest that you feel influenced or controlled by external forces, leading you to question your reality. The sensation of having been there for years but feeling like only hours highlights a disconnection from time, possibly reflecting feelings of monotony or being stuck.

The corrupted nun figure might symbolize a loss of innocence or a moral dilemma you’re grappling with. Your pleading to not go with her suggests a strong desire to resist negative influences or paths that could lead to harm. The chase indicates a feeling of urgency or threat, and the separation from your parents could reflect fears of abandonment or feeling unsupported in a challenging situation.

The skateboarder in the alley, representing a change in appearance yet carrying a similar threat, could symbolize the idea that dangers may come in different forms and that you're facing a cycle of fear or anxiety that feels inescapable. The screaming might represent your inner turmoil or a plea for help.

Overall, this dream could be a manifestation of anxieties, fears of losing control, or feelings of being overwhelmed. It might be helpful to reflect on areas of your life where you feel trapped or influenced by others and consider how you can reclaim your sense of agency and direction.
