The Privy
Scholars have said that if one dreams of being placed in a privy (toilet), it may indicate that a plot or deception will be planned against them. If the door is closed upon them inside the privy, it might suggest the approach of their death.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
