Thank you for sharing your dream with us. Please take everything that I share back to the Holy Spirit as He Alone gives the accurate interpretation.
You ask a good question about the meaning of toilets of dreams and the answer is “It depends on the context of the dream.” The usage of toilets in the context of your dream is unique or one can say is not the “classic” definition. In the context of your dream, think of three public ministries/associations/groups/people (this includes online as well) where you go to “decompress” your emotions/feelings/or things bothering you. Hopefully that will help you understand what is going on in your dreams/life. Pray for God’s guidance as to which groups/ministries to be involved in that are “clean”. In other words be selective as to who/what ministries/people to share intimate issues that you might be dealing with and/or for counsel.
