Dreams involving churches often symbolize your inner beliefs, values, and a sense of community or spirituality. The church crumbling can represent a significant change or upheaval in your life, possibly related to your beliefs or moral dilemmas.

The act of lurking and initially having harmful intentions suggests a struggle with darker thoughts or feelings about certain situations or people in your life. However, your instinct to help the children and others escape indicates an underlying desire to do good or protect innocence, despite the chaos you've contributed to.

The slide with the grater might symbolize the risks involved in navigating your current situation. It reflects the need for caution as you deal with potential harm or consequences in your life.

Overall, this dream could be prompting you to reflect on your motivations and the impact of your actions on others. Consider what aspects of your life are causing you to feel conflicted or to question your values. It might be beneficial to explore these feelings further and find ways to align your actions with your true intentions.
