Changing the Bed
Scholars have said that seeing a person change their bed and move to another signifies marrying another woman, and they might divorce their first wife if their intention is not to return to the first bed. If the first bed changes to an unfavorable state in interpretation, it may indicate the wife's death or harm befalling her. However, if it transforms into a favorable state, it suggests reconciling with the first wife with an improvement in her condition.
