The Angel (Transformation)
Interpreters mention that whoever sees themselves transformed into the form of an angel in a dream, it may carry different connotations depending on the dreamer's state. If they are in distress, it might indicate relief, and if enslaved, they might be freed. If honorable, they might attain leadership, but if the dreamer is ill, this vision could suggest their approaching death.
