Entering the Hot Room
Interpreters believe that entering the hot room of a bathhouse carries an opposite interpretation to exiting it. As for a sick person sitting in the middle room, it may indicate that their illness is moderate until they exit or enter, leading to either a relapse or recovery. If the dreamer is not sick and has a dispute or need with a ruler, judgment may be in their favor or against them depending on what they experienced in the bathhouse regarding heat, cold, or slipping. If none of these apply and the dreamer is single, they might marry or attend a feast or funeral, or receive money from a ruler. Sweat may also indicate worry, fatigue, and illness, and if the dreamer is naked, matters relate to his wife, while if dressed, they relate to a foreign or forbidden party.
