This is an unusual dream which features a common, everyday function. One night, I dreamed that a female stranger asked to use the toilet in my home. She was walking on the road when she felt she had to use a toilet so she knocked on my door. She made her request. Standing beside her was a man, who took offence at her request. He shouted at her, “You should not ask to use her toilet!” I felt anxious because the two strangers were verbally disagreeing and maybe fighting, at my doorstep. The dream ended there.
Why did I see this dream? Its probably because I had experienced times when I needed to use a toilet, while outdoors shopping or walking in-between destinations. There are only toilets for public use inside shopping malls, public amenities like market, food court, public transport stations, public usage buildings like library, hospital, clinic, designated walking path along the beach opened to public use and etc. If a person is walking on the road, there is unlikely to be a facility where toilets are available for public use.
Anxiety over situations and places can trigger dreams associated with the theme. I may have caused this dream when an old memory about searching for a public toilet, was activated by some reason. One of the reasons could be using a public toilet during my daytime. A dirty toilet that made a bad impression could also trigger a dream about a toilet.
Being unable to go to toilet in a calm and ordinary manner has a latent meaning in dream analysis. It can mean insecurity and instability in real life. When a basic human function is denied, it can mean there is no stability in life.
